WebbNote: The reactive power absorbed by the capacitance is negative and the current's phase—that is, the phase of i(t) —leads that of v(t). Be careful here. Absorbed reactive power is describe s stored energy being swapped between the element and other parts of the circuit. Reactive power does not refer to average power being absorbed. WebbReactive power is given by Q = V I Sinθ which can be positive (+ve) for inductive loads and negative (-ve) for capacitive load.. The unit of Reactive Power is Volt-Ampere reactive i.e. VAR where 1 VAR = 1V x 1A.. In more simple words, in Inductor or Capacitor, how much magnetic or electric field produced by 1A x 1V is known as the unit of Reactive Power.
