In alternating current power transmission and distribution, volt-ampere reactive (var) is a unit used to measure reactive power in an AC electric power system. A VAR is essentially magnetic power, which causes a phase shift between voltage and current sine wave curves. The correct symbol is var and not Var, but the latter is widely used.

Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. In alternating current power transmission and distribution, volt-ampere reactive (var) is a unit used to measure reactive power in an AC electric power system. A VAR is essentially magnetic power, which causes a phase shift between voltage and current sine wave curves. The correct symbol is var and not Var, but the latter is widely used. The term var was proposed by the Romanian Professor Constantin Budeanu and introduced in 1930 by the IEC in Stockholm, which has adopted it as the unit for reactive power.Vars may be considered as either the imaginary part of apparent power, or the peak power flowing into a reactive load, where voltage and current are specified in volts and amperes. The two definitions are equivalent.
