Q. An inductor $L,$ a resistance $R$ and two identical bulbs, $B_{1}$ and $B_{2}$ are connected to a battery through a switch $S$ as shown in the figure. The resistance $R$ is the same as that of the coil that makes $L$. Which of the following statements gives the correct description of the happenings when the switch $S$ is closed
A) The bulb $B_{2}$ lights up earlier than $B_{1}$ and finally both the bulbs shine equally bright
B) $B_{1}$ light up earlier and finally both the bulbs acquire equal brightness
C) $B_{2}$ lights up earlier and finally $B_{1}$ shines brighter than $B_{2}$
D) $B_{1}$ and $B_{2}$ light up together with equal brightness all the time
Explanation
The correct answer is Option C: $B_{2}$ lights up earlier and finally $B_{1}$ shines brighter than $B_{2}$.
