if the load is reactive then what is the use of calculating
the real power and what is the use of reactive power
if my question is wrong please excuse me..
Answer / sagar upadhyay
If the load is purely reactive, then there is no need to find
out real power since it will be zero. But if there is some
resistance in the circuit, real power tells us the loss in
the resistor.
Reactive power is used to measure the power factor of the
circuit. since, higher the pf, higher will be the power
quality of the circuit. We always try to reduce the reacive
power keeping apparent power constant & in this way pf is
improved.

1. If we apply dc supply to the primary winding of transformer it will be burnt out. similarly dc supply is given to field winding of syn. motor and armature winding of dc motor, they are safe. (Remember both windings inductive nature) what is the reason behind that?
