Two electric bulbs marked 25W - 220V and 100W - 220V are connected in series to a 440V supply. Which of the bulbs will fuse?

A

Both

B

100W

C

50W

D

None of these

Text Solution

Verified by Experts

As, the rated power of 25W is less than 100W, it implies that 25W bulb has higher resistance. As in series connection, current through both the bulbs is same but heating in 25W bulb is more than that of 100W bulb. So, 25W bulb will get fused.
