Vedclass · Answer

(D) For figure $(a)$,at $t = 0$,the capacitor is uncharged,so the charge is $0$. Just after $t = 0$,the capacitor acts as a short circuit,so the current is $I = E/R$.Long after $t = 0$ $(t 	o \infty)$,the capacitor is fully charged and acts as an open circuit. The potential difference across the capacitor equals the $EMF$ of the battery $E$. Thus,the charge $q = EC$.For figure $(b)$,long after $t = 0$ $(t 	o \infty)$,the inductor acts as a short circuit (ideal inductor with zero resistance). The current in the circuit is determined by the resistor $R$. Thus,$I = E/R$.Therefore,both statements $(B)$ and $(C)$ are correct.

The switches in figures $(a)$ and $(b)$ are closed at $t = 0$.
