Define reactive power.
Understand the Problem
The question is asking for a definition of reactive power, which is a concept in electrical engineering related to the power that oscillates between the source and load in an AC system. It is important in understanding the efficiency and stability of power systems.
Answer
Reactive power is the power released and stored by capacitors and inductors, measured in VAR or kVAR.
Reactive power is the power, measured in VAR or kVAR, released and stored by capacitors and inductors. It flows back and forth between the source and the reactive components, affecting the power factor of a circuit.
Answer for screen readers
Reactive power is the power, measured in VAR or kVAR, released and stored by capacitors and inductors. It flows back and forth between the source and the reactive components, affecting the power factor of a circuit.
More Information
Reactive power does not perform any real work, but is essential in the regulation of voltage and the management of power distribution in AC circuits.
Tips
A common mistake is confusing reactive power with active or apparent power. Reactive power does not do any real work but is necessary for the transport of real power.
