Further, the units are not watts, but … WebThe power in an inductive circuit is known as Reactive Power or volt-amps reactive, symbol Var which is measured in volt-amps. In a RL series AC circuit, the current lags the supply …

WebAs was shown earlier, the current has a phase shift of +90° with respect to the voltage. If we represent these phase angles of voltage and current mathematically, we can calculate the phase angle of the capacitor’s reactive opposition to current. Voltage lags current by 90° in … In electric power transmission and distribution, volt-ampere reactive (var) is a unit of measurement of reactive power. Reactive power exists in an AC circuit when the current and voltage are not in phase. The term var was proposed by the Romanian electrical engineer Constantin Budeanu and introduced in 1930 by the IEC in Stockholm, which has adopted it as the unit for reactive power. Special instruments called varmeters are available to measure the reactive power in a circuit.
