Instantaneous power in inductor is proportional to the
Asquare of instantaneous current.
Bproduct of the instantaneous current and rate of change of current.
CTemperature of the inductor.
Dsquare of the rate of change of current.
Correct answer
B. product of the instantaneous current and rate of change of current.
Explanation
The instantaneous voltage across the inductor is expressed as the product of inductance and rate of change of current through it. Power is expressed as the product of current and voltage. Hence instantaneous power in an inductor is proportional to the product of instantaneous current and rate of change of current through it.
