Description : In a pure resistive circuit, the average power Pavg is ______ the peak power Pmax. (1) Double (2) One-half of (3) One-fourth (4) Equal to
Answer : In a pure resistive circuit, the average power Pavg is One-half of the peak power Pmax.
Description : In a purely inductive circuit?
Answer : In a purely inductive circuit actual power is zero.
Description : In a pure resistive circuit?
Answer : In a pure resistive circuit current is in phase with the voltage.
Description : Briefly explain how the power factor of an inductive circuit can be improved.
Answer : As we know that power factor should be corrected to ensure that the current supplied is cost friendly. Meaning the power factor should be around one but not greater than one(0.8-0.9) in a ... an inductive circuit due to the inductive reactance which oppose the change of current in the ac circuit.
Description : The power factor of a D.C. circuit is always?
Answer : The power factor of a D.C. circuit is always unity.
