Answer 2

The torch bulb which normally works at 4.5V will get fused when connected to an electricity supply of 220V.

• A bulb that works on 4.5V of electricity will not be able to bear a high voltage of 220V.
• On receiving a supply of 220V, the filament present inside the bulb will melt due to the heat generated.
• This meltdown will break the circuit and the bulb will stop glowing.
• The bulb in the situation will get fused and will have to be replaced.
