What is reactive power and active power?

 Active power is the power which is actually generated by generator.At the user-end or consumer-end we take this power. Active power is responsible to supply the required power to the loads. Whereas Reactive power is opposing power of active power ,which is created by load. For inductive loads reactive power is more, so we are using capacitor banks in system to improve power factor then reactive power decreases.

                  

Apparent Power=Active Power+Reactive Power 
or
Active Power=VI Cos(Phase Angle)
Reactive Power=VI Sin(Phase Angle)
Apparent Power= VI
