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 bulbs will fuse
Text Solution
Verified by ExpertsThe correct answer is:
B
Resistance of 25 W bulb 
Its safe current 
Resistance of 100 W bulb 
Its safe current 
When connected in series to 440 V supply, then the current 
Thus current is greater for 25 W bulb, so it will fuse.
