Please answer the following question: Information:  - Electric power transmission is the bulk movement of electrical energy from a generating site, such as a power plant, to an electrical substation. The interconnected lines which facilitate this movement are known as a transmission network. This is distinct from the local wiring between high-voltage substations and customers, which is typically referred to as electric power distribution. The combined transmission and distribution network is known as the "power grid" in North America, or just "the grid". In the United Kingdom, the network is known as the "National Grid".  - The coulomb (unit symbol: C) is the International System of Units (SI) unit of electric charge. It is the charge (symbol: "Q" or "q") transported by a constant current of one ampere in one second:   - Voltage, electric potential difference, electric pressure or electric tension (formally denoted or , but more often simply as "V" or "U", for instance in the context of Ohm's or Kirchhoff's laws) is the difference in electric potential energy between two points per unit electric charge. The voltage between two points is equal to the work done per unit of charge against a static electric field to move the test charge between two points and is measured in units of "volts" (a joule per coulomb).  - In physics, potential energy is energy possessed by a body by virtue of its position relative to others, stresses within itself, electric charge, and other factors.  Common types include the gravitational potential energy of an object that depends on its mass and its distance from the center of mass of another object, the elastic potential energy of an extended spring, and the electric potential energy of an electric charge in an electric field. The unit for energy in the International System of Units (SI) is the joule, which has the symbol "J".  - Colorado is a state in the United States encompassing most of the Southern Rocky Mountains as well as the northeastern portion of the Colorado Plateau and the western edge of the Great Plains. Colorado is part of the Western United States, the Southwestern United States, and the Mountain States. Colorado is the 8th most extensive and the 22nd most populous of the 50 United States. The United States Census Bureau estimates that the population of Colorado was 5,456,574 on July 1, 2015, an increase of 8.50% since the 2010 United States Census.  - A high-voltage, direct current (HVDC) electric power transmission system (also called a power super highway or an electrical super highway) uses direct current for the bulk transmission of electrical power, in contrast with the more common alternating current (AC) systems. For long-distance transmission, HVDC systems may be less expensive and suffer lower electrical losses. For underwater power cables, HVDC avoids the heavy currents required to charge and discharge the cable capacitance each cycle. For shorter distances, the higher cost of DC conversion equipment compared to an AC system may still be justified, due to other benefits of direct current links.  - Alternating current (AC), is an electric current which periodically reverses polarity, whereas direct current (DC, also dc) flows only in one direction with a single polarity either positive or negative. Alternating current is the form in which electric power is delivered to businesses and residences, and it is the form of electric energy that consumers typically use when they plug kitchen appliances, televisions and electric lamps into a wall socket. A common source of DC power is a battery cell in a flashlight. The abbreviations "AC" and "DC" are often used to mean simply "alternating" and "direct", as when they modify "current" or "voltage".  - An electric potential (also called the "electric field potential" or the "electrostatic potential") is the amount of electric potential energy that a unitary point electric charge would have if located at any point in space, and is equal to the work done by an external agent in carrying a unit of positive charge from the arbitrarily chosen reference point (usually infinity) to that point without any acceleration.   - A county seat is an administrative center, seat of government, or capital city of a county or civil parish. The term is used in the United States, Canada, Romania, China and Taiwan. In the United Kingdom and Ireland, county towns have a similar function.  - The joule, symbol J, is a derived unit of energy in the International System of Units. It is equal to the energy transferred to (or work done on) an object when a force of one newton acts on that object in the direction of its motion through a distance of one metre (1 newton metre or N·m). It is also the energy dissipated as heat when an electric current of one ampere passes through a resistance of one ohm for one second. It is named after the English physicist James Prescott Joule (18181889).  - An electric field is a vector field that associates to each point in space the Coulomb force that would be experienced per unit of electric charge, by an infinitesimal test charge at that point. Electric fields converge and diverge at electric charges and can be induced by time-varying magnetic fields. The electric field combines with the magnetic field to form the electromagnetic field.  - Electric potential energy, or electrostatic potential energy, is a potential energy (measured in joules) that results from conservative Coulomb forces and is associated with the configuration of a particular set of point charges within a defined system. An "object" may have electric potential energy by virtue of two key elements: its own electric charge and its relative position to other electrically charged "objects".  - Nebraska is a state that lies in both the Great Plains and the Midwestern United States. The state is bordered by South Dakota to the north, Iowa to the east and Missouri to the southeast, both across the Missouri River, Kansas to the south, Colorado to the southwest and Wyoming to the west. Its area is just over 77,220 sq mi (200,000 km) with almost 1.9 million people. Its state capital is Lincoln. Its largest city is Omaha, which is on the Missouri River.  - A census is the procedure of systematically acquiring and recording information about the members of a given population. It is a regularly occurring and official count of a particular population. The term is used mostly in connection with national population and housing censuses; other common censuses include agriculture, business, and traffic censuses. The United Nations defines the essential features of population and housing censuses as "individual enumeration, universality within a defined territory, simultaneity and defined periodicity", and recommends that population censuses be taken at least every 10 years. United Nations recommendations also cover census topics to be collected, official definitions, classifications and other useful information to co-ordinate international practice.  - The Great Plains is the broad expanse of flat land (a plain), much of it covered in prairie, steppe and grassland, that lies west of the Mississippi River tallgrass prairie states and east of the Rocky Mountains in the United States and Canada. This area covers parts, but not all, of the states of Colorado, Kansas, Montana, Nebraska, New Mexico, North Dakota, Oklahoma, South Dakota, Texas, and Wyoming, Minnesota, Iowa and the Canadian provinces of Alberta, Manitoba and Saskatchewan. The region is known for supporting extensive cattle ranching and dry farming.  - The volt (symbol: V) is the derived unit for electric potential, electric potential difference (voltage), and electromotive force. The volt is named in honour of the Italian physicist Alessandro Volta (17451827), who invented the voltaic pile, possibly the first chemical battery.  - Electric power is the rate, per unit time, at which electrical energy is transferred by an electric circuit. The SI unit of power is the watt, one joule per second.  - Electric charge is the physical property of matter that causes it to experience a force when placed in an electromagnetic field. There are two types of electric charges: positive and negative. Like charges repel and unlike attract. An object is negatively charged if it has an excess of electrons, and is otherwise positively charged or uncharged. The SI derived unit of electric charge is the coulomb (C). In electrical engineering, it is also common to use the ampere-hour (Ah), and, in chemistry, it is common to use the elementary charge ("e") as a unit. The symbol "Q" often denotes charge. Early knowledge of how charged substances interact is now called classical electrodynamics, and is still accurate for problems that don't require consideration of quantum effects.  - Kansas is a U.S. state located in the Midwestern United States. Its capital is Topeka and its largest city is Wichita. Kansas is named after the Kansa Native American tribe, which inhabited the area. The tribe's name (natively "") is often said to mean "people of the wind" or "people of the south wind", although this was probably not the term's original meaning. For thousands of years, what is now Kansas was home to numerous and diverse Native American tribes. Tribes in the eastern part of the state generally lived in villages along the river valleys. Tribes in the western part of the state were semi-nomadic and hunted large herds of bison.  - Sidney is a city and county seat of Cheyenne County, Nebraska, United States. The population was 6,757 at the 2010 census.  - An ion is an atom or a molecule in which the total number of electrons is not equal to the total number of protons, giving the atom or molecule a net positive or negative electrical charge. Ions can be created, by either chemical or physical means, via ionization.  - The Missouri River is the longest river in North America. Rising in the Rocky Mountains of western Montana, the Missouri flows east and south for before entering the Mississippi River north of St. Louis, Missouri. The river takes drainage from a sparsely populated, semi-arid watershed of more than half a million square miles (1,300,000 km), which includes parts of ten U.S. states and two Canadian provinces. When combined with the lower Mississippi River, it forms the world's fourth longest river system.  - Pressure (symbol: "p" or "P") is the force applied perpendicular to the surface of an object per unit area over which that force is distributed. Gauge pressure (also spelled "gage" pressure) is the pressure relative to the ambient pressure.  - Direct current (DC) is the unidirectional flow of electric charge. Direct current is produced by sources such as batteries, power supplies, thermocouples, solar cells, or dynamos. Direct current may flow in a conductor such as a wire, but can also flow through semiconductors, insulators, or even through a vacuum as in electron or ion beams. The electric current flows in a constant direction, distinguishing it from alternating current (AC). A term formerly used for this type of current was galvanic current.  - The Midwestern United States, also referred to as the American Midwest or simply the Midwest, is one of the four geographic regions defined by the United States Census Bureau, occupying the northern central part of the United States of America. It was officially named the North Central region by the Census Bureau until 1984.  - The ohm (symbol: ) is the SI derived unit of electrical resistance, named after German physicist Georg Simon Ohm. Although several empirically derived standard units for expressing electrical resistance were developed in connection with early telegraphy practice, the British Association for the Advancement of Science proposed a unit derived from existing units of mass, length and time and of a convenient size for practical work as early as 1861. The definition of the ohm was revised several times. Today the definition of the ohm is expressed from the quantum Hall effect.  - South Dakota is a state located in the Midwestern region of the United States. It is named after the Lakota and Dakota Sioux Native American tribes, who compose a significant portion of the population and historically dominated the entire territory. South Dakota is the 17th most expansive, but the 5th least populous and the 5th least densely populated of the 50 United States. Once the southern portion of the Dakota Territory, South Dakota became a state on November 2, 1889, simultaneously with North Dakota. Pierre is the state capital and Sioux Falls, with a population of about 171,000, is South Dakota's largest city.  - Capacitance is the ability of a body to store an electric charge. There are two closely related notions of capacitance: "self capacitance" and "mutual capacitance", that are usually both designated by the same term "capacitance". A material with a large self capacitance holds more electric charge at a given voltage, than one with low capacitance. Any object that can be electrically charged exhibits self capacitance. The notion of mutual capacitance is particularly important for understanding the operations of the capacitor, one of the three fundamental electronic components (along with resistors and inductors).  - Wyoming is a state in the mountain region of the western United States. The state is the tenth largest by area, the least populous and the second least densely populated state in the country. Wyoming is bordered on the north by Montana, on the east by South Dakota and Nebraska, on the south by Colorado, on the southwest by Utah, and on the west by Idaho. Cheyenne is the capital and the most populous city in Wyoming, with a population estimate of 63,335 in 2015. The state population was estimated at 586,107 in 2015, which is less than the population of 31 of the largest U.S. cities.  - Virginia Smith Converter Station is a High - voltage direct current ( HVDC ) back - to - back station near Sidney , Nebraska at 41 ° 09  51 `` N 102 ° 59  15 '' W named for former Congresswoman Virginia Smith , a Nebraska Republican who represented Nebraska 's 3rd congressional district from 1975 to 1991 . Virginia Smith Converter Station was built by Siemens and began service in 1988 . The station can transfer a maximum power of 200 megawatts ; the voltage used by the station is 55.5 kV . Timing differences in continental - sized nations make national power grids based solely on conventional alternating current impossible . However , power can be transferred over longer distances and between separate AC grids by conversion to direct current during transmission , and conversion to alternating current in phase with the local line frequency at the delivery point . By the early 21st century , high - power semiconductors began to make the more difficult DC - to - AC conversion technically and economically possible at the high power levels needed in power grids . The Virginia Smith Converter station is significant for being the first interchange between eastern and western United States electrical grids .  - Missouri (see pronunciations) is a state in the Midwestern region of the United States, achieving statehood in 1821. With over six million residents, it is the eighteenth most populous state and host to the mean center of United States population. The largest urban areas are St. Louis, Kansas City, Springfield, and Columbia. The capitol is in Jefferson City on the Missouri River. The state is the twenty-first most extensive by area and is geographically diverse. The Northern Plains were once covered by glaciers, then tallgrass prairie, and now the deep soils yield great agricultural productivity. In the South are the Ozarks, a forested highland, providing timber, minerals, and recreation. The Mississippi River forms the eastern border of the state, eventually flowing into the swampy Missouri Bootheel.  - Nebraska's 3rd congressional district seat encompasses the western three-fourths of the state; it is one of the largest non-at-large Congressional districts in the country, covering nearly , two time zones and 68.5 counties.
