The bulb will light up for an instant when the capacitor starts charging.

(A) When the switch $S$ is closed,the capacitor begins to charge. Initially,the capacitor acts as a short circuit (zero resistance),allowing current to flow through the circuit,which causes the bulb to light up for an instant. As the capacitor charges,the potential difference across it increases,and the current in the circuit decreases. Once the capacitor is fully charged,it acts as an open circuit,blocking the flow of direct current $(DC)$. Therefore,the current becomes zero,and the bulb stops glowing.

After the switch shown in Figure $A$ is closed,there is a current $i$ through the resistance $R$. Figure $B$ indicates current variation curves $a, b, c,$ and $d$ for four sets of values of $R$ and capacitance $C$:
$(i)$ $R_0$ and $C_0$
$(ii)$ $2R_0$ and $C_0$
$(iii)$ $R_0$ and $2C_0$
$(iv)$ $2R_0$ and $2C_0$
Which set goes with which curve?
