Calculate the active power in a 11710 H inductor.(a) 8245 W(b) 1781 W(c) 0 W(d) 1964 WThis question was addressed to me in an interview for job.I need to ask this question from Solar Panels in division Solar and Battery Powered Drives of Electric Drives

Answer»

The CORRECT option is (c) 0 W

For 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.
