Question

If two bulbs of wattage 25 and 100 respectively each rated at 220 volt are connected in series with the supply of 440 volt, then which bulb will fuse

• A. 100 watt bulb
• B. 25 watt bulb
• C. None of them
• D. Both of them

Answer 1

Answer: (B)

25 watt bulb

Answer 2

In series $V_{A} \propto \frac{1}{P_{R}}$ i.e. voltage appear on 25W bulb will be more then the voltage appears on 100 W bulb. So bulb of 25 W will gets fused.
