Alternating current — (green curve). The horizontal axis measures time; the vertical, current or voltage. In alternating current (AC, also ac) the movement of electric charge periodically reverses direction. In direct current (DC, also dc), the flow of electric charge … Wikipedia
History of electric power transmission — In the early days of commercial use of electric power, electric power transmission restricted the distance between generating plant and consumers. Originally generation was with direct current, which could not easily be increased in voltage for… … Wikipedia
Power transmission — is the movement of energy from its place of generation to a location where it is applied to performing useful work.Power is defined formally as units of energy per unit time.In SI units: 1 watt = 1 joule/s = 1 newton * metre/second… … Wikipedia
Alternating current — Al ter*nat ing cur rent (Elec.) A current which periodically changes or reverses its direction of flow, especially an electric current that reverses direction sinusoidally, as is used for most domestic and industrial power requirements.… … The Collaborative International Dictionary of English
alternating current (AC) — Flow of electric charge that reverses periodically, unlike direct current. It starts from zero, grows to a maximum, decreases to zero, reverses, reaches a maximum in the opposite direction, returns again to zero, and repeats the cycle… … Universalium
