Questions
Two bulbs rated and are connected in series to a 440 V line. which one is likely to fuse?
detailed solution
Correct option is A
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.Talk to our academic expert!
