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

Resistance of 25 W bulb =  220  ×  22025 = 1936 ΩIts safe current =2201936 = 0.11  AResistance of 100 W bulb =  220  ×  220100 = 484  ΩIts safe current =220484 = 0.48  AWhen connected in series to 440 V supply, then thecurrent I=4401936+484 = 0.18  A
