Q. In a choke coil, the reactance $X_{L}$ and resistance R are such that
A) $X_{L} = R$
B) $X_{L} > > R$
C) $X_{L} < < R$
D) $X_{L} = \infty$
Explanation
(b) To decrease current in an AC circuit, choke coil is used. The choke coil has high inductance and negligible resistance, so that the energy loss in the circuit is negligible.
Hence, $X_{L} > > R$
