Reactive Power Calculator

Enter the true power and the apparent power into the calculator to determine the reactive power.

Reactive Power Formula

The following formula is used to calculate an reactive power value.

RP = SQRT ( AP^2 – TP^2)

  • Where RP is the reactive power
  • AP is the apparent power
  • TP is the true power.


FAQ

What is reactive power?

A reactive power is the total power, known as volts times amperes, that are out-of-phase with each other. It’s the portion of electricity that sustains the electric and magnetic fields needed for alternating current equipment.
