Q.

Calculate the active power in a 11710 H inductor.

A. 8245 w
B. 1781 w
C. 0 w
D. 1964 w
Answer» C. 0 w
Explanation: the inductor is a linear element. it only absorbs reactive power and stores it in the form of oscillating energy. the voltage and current are 90° in phase in case of the inductor so the angle between v & i is 90°. p = vicos90° = 0 w.
