State what power is measured in and its units
WebReactive Power. We know that reactive loads such as inductors and capacitors dissipate zero power, yet the fact that they drop voltage and draw current gives the deceptive impression that they actually do dissipate power.. This “phantom power” is called reactive power, and it is measured in a unit called Volt-Amps-Reactive (VAR), rather than watts.. … WebThe electric current is measured in ampere. One ampere of current represents one coulomb of electric charge moving past a specific point in one second. 1 ampere = 1 coulomb / 1 second The conventional direction of an electric current is the direction in which a positive charge would move.
