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