What is the difference between active power and reactive power?

Question

Accepted Answer

Active power is the actual power consumed by a circuit, while reactive power is the power that flows back and forth between the circuit and the source without being consumed.

Active power is measured in watts (W) and represents the real power used to perform work in a circuit.
Reactive power is measured in volt-amperes reactive (VAR) and represents the power oscillating between the circuit and the source due to inductive or capacitive loads.
The combination of active power and reactive power gives the total power in a circuit, measured in volt-amperes (VA).
Power factor is the ratio of active power to total power, indicating how efficiently power is being used in a circuit.
