In the circuit shown in the 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,the 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.
