Assertion :In a chain of bulbs, 50 bulbs are joined in series. One bulb is removed now. If the remaining 49 bulbs are again connected in series across the same supply then current flowing in each bulb increases. Reason: The resistance of 49 bulbs will be more than 50 bulbs.

Both Assertion and Reason are correct and Reason is the correct explanation for Assertion

Solution

The correct option is C Assertion is correct but Reason is incorrect
Since the bulbs are joined in series, so when one bulb is removed from chain then the resistance of the chain is decreases, hence current flowing through each bulb is increased.
and because all resistors are connected in series so total resistance of 50 bulbs will be more than total resistance of 49 bulbs.
