Q. A coil of inductance $L$ has an inductive reactance of $X_{L}$ in an AC circuit in which the effective current is $l$. The coil is made from a super-conducting material and has no resistance. The rate at which power is dissipated in the coil is
A) 0
B) $IX_{L}$
C) $I^{2}X_{L}$
D) $IX_{L}^{2}$
Explanation
(a) For purely $L$-circuit $P = 0$
