Electrical load is of three types:
Inductive load,
Resistive load and
Capacitive load.

The power drawn in a circuit will depend on type of load, the power is supplied. The circuit which has inductance in the network is inductive circuit. Hence inductive load has resistance and inductance in the network.

Power has two components - Active and Reactive power.

Power required to supply resistive component of load is called active power. This is actual energy supplied to run the motor if the load is a motor. This electrical energy is converted into mechanical energy as output. The reactive component of power is supplied to over come inductive component of load. This reactive power is requried to maintain the supply voltage. Hence the inductive load draws both active and reactive power. The active power is supplied to Generator from Turbine which is coupled with generator and reactive power is supplied by Exciter, the field component to maintain rated voltage.
