Learn MoreReactive Power can best be described as the quantity of "unused" power that is developed by reactive components in an AC circuit or system. In a DC circuit, the product of "volts x amps" gives the power consumed in watts by the circuit. However, while this formula is also true for purely resistive AC circuits, the situation is slightly ...
