If two bulbs of wattages 25 W and 100 W respectively each rated by 220 V are connected in series with the supply of 440 V then which bulb will fuse?
Text Solution
Verified by ExpertsThe correct answer is:
B
Resistance of 25 W bulb
Resistance of 100 W bulb
Series resistance 
Current through series combination will be,
Thus the bulb of 25 W will be fused because it can tolerate only 220 V while the voltage across it is 352 V .
