Question

Two bulbs rated 25  W220V and 100  W220V are connected in series to a 440 V line. which one is likely to fuse?

Easy
Solution

The resistance of 25 W bulb will be higher than 100 W bulb. So when connected in series across 440 V, potential difference across 25 W bulb will be more than 220 V. Hence, this bulb is likely to fuse.
