In the circuit shown in figure, if both the bulbs $B_1$ and $B_2$ are identical then

A

Both bulbs have equal brightness

B

$B_2$ will be brighter than $B_1$

C

As the frequency is increased, brightness of $B_1$ will increase and that of $B_2$ will decrease

D

As the frequency is decreased, the brightness of $B_1$ will increase and that of $B_2$ will decrease

Solution

(c)

As frequency is increased, $X_C$ will decrease and $X_L$ will increase, so brightness of $B$, will increase and that of $B_2$ will decrease.
