Answer:
When connected in series, the voltages divide in them in the ratio of their resistances. The voltage of 440V divides in such a way that voltage across 25W bulb will be more than 220V. Hence 25Wbulb will fuse.

Answer:
hey friend here your answer
Well it's simple power = V*I
To get I =P/V =500/2
=2amp
By ohms law R=V/I
=250/2
=125 ohms
I hope it's help you
