Q. In a choke coil, the resistance $X_{L}$ and resistance $R$ are such that
A) $X_{L} = R$
B) $X_{L} \gg R$
C) $X_{L} \ll R$
D) $X_{L} = \infty$
Explanation
(b) A choke coil is an electrical appliance used for controlling current in an a.c. circuit. In a choke coil $R \ll X_{L}$ to avoid power dissipation
