Q140 / 155 · WBJEE 2021 · Physics

Consider a pure inductive A.C. circuit as shown in the figure. If the average powr consumed is $P$, then

A
$P>0$
B
$\quad P < 0$
Correct answer
C
$P=0$
D
$\mathrm{P}$ is infinite

Solution

Pure inductor consumer no power as I and $\mathrm{V}$ are in $90^{\circ}$ phase difference.

Hence, the correct answer is option: 'C'.
