Assertion : If three identical bulbs are connected in series as shown

1.	Assertion : If three identical bulbs are connected in series as shown in figure then on closing the switchs. Bulb `C` short circuited and hence illumination of bulbs `A` and `B` decreases. Reason : Voltage on `A` and `B` decreases A. If both assertion and reason are ture and reason is the correct explanation of assertion.B. If both assertion and reason are true but reason is not the correct explanation of assertion.C. If assertion is true but reason is false.D. If assertion and reason both are false.
Answer» Correct Answer - D (d) When switch `S` is closed, bulb `C` is short circuited, so voltage `V` distributes only in two parts i.e., voltage on Bulb `A` and `B` increases as compared previously. Hence illumination of Bulb `A` and `B` increases.
