Vedclass · Answer

(D) Statement-$I$ is true because a capacitor can be used to limit current in an $a.c.$ circuit without dissipating power, similar to a choke coil.Statement-$II$ is true because the capacitive reactance $X_C = 1 / (2\pi f C)$. For $d.c.$, $f = 0$, so $X_C = \infty$ (blocking $d.c.$), while for $a.c.$, it offers finite reactance.Since a capacitor provides reactance to limit current in $a.c.$ circuits without power loss, Statement-$II$ correctly explains why it can replace a choke coil.

Statement-$I$: $A$ capacitor can be used in an $a.c.$ circuit in place of a choke coil.
Statement-$II$: $A$ capacitor blocks $d.c.$ and allows $a.c.$ to pass.
