How alternating current is generated

WebAlternating currents are accompanied by alternating voltages. An AC voltage v can be described mathematically as a function of time by the following equation:. where. V peak is the peak voltage (unit: volt),; ω is the angular frequency (unit: radians per second) . The angular frequency is related to the physical frequency, f, which represents the number of … Webdirect current, abbreviation DC, flow of electric charge that does not change direction. Direct current is produced by batteries, fuel cells, rectifiers, and generators with commutators. Direct current was supplanted by alternating current (AC) for common commercial power in the late 1880s because it was then uneconomical to transform it to …
