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

## Apparent Power Formula

The following formula is used to calculate the apparent power of a system.

A = Sqrt ( TP^2 + RP^2)

A = I^2 * Z

- Where A is the apparent power (kVA)
- TP is the true power (kW)
- RP is the reactive power (kVAR)
- I is the impedance current
- Z is the impedance

## Apparent Power Definition

An apparent power is a measure of the combination of reactive power and true power in a circuit.

## Apparent Power Example

How to calculate apparent power?

**First, determine the true power.**Calculate the true power of the circuit.

**Next, determine the reactive power.**Calculate the reactive power of the circuit.

**Finally, calculate the apparent power.**Calculate the apparent power using the formula provided above.

## FAQ

**What is an apparent power?**

An apparent power is a measure of the combination of the reactive power and the true power of a circuit. in other words, it’s product of the voltage and current while not referencing phase angle.
