When the switch $S$ is opened,which of the following statements will be correct about the current flowing through the battery $B$?

  • A
    $A$ finite and constant current will flow
  • B
    $A$ finite current will flow initially that will decrease exponentially with time
  • C
    No current will flow
  • D
