# Real and Reactive Power Calculator

The reactive power also called as a Volt-Ampere Reactive (VAR), whereas the real power is also called as the actual power, true power, Watt-full Power, useful power, and active power. Use our online real and reactive power calculator to know the real power and reactive power for the given voltage and current. This active and reactive power calculator can be used for reactive and active power calculation of both single phase power and three-phase power.

For Single Phase t = v × i × cos(p) r = v × i × sin(p) For Three Phase t = √3 × v × i × cos(p) r = √3 × v × i × sin(p) Where, t = Real power r = Reactive power v = Voltage i = Current p = Phase Angle

### Example:

Calculate the real and reactive power for both the single and three phase with the voltage of 50 V, current of 30 Amps and phase angle of 45°.

#### Solution:

Single Phase:
t = 50 × 30 × cos(45)
= 1060.6602 watts
r = 50 × 30 × sin(45)
= 1060.6602 watts
Three Phase:
t = √3 × 50 × 30 × cos(45)
=1837.1173 watts
r = √3 × 50 × 30 × sin(45)
= 1837.1173 watts
