An electric bulb is connected to a cell through a switch as shown in figure. When the switch is brought in ‘ON’ position, the bulb does not glow. What could be the possible reason/s for it? Mention any two of them.


After bringing the switch to the 'ON' position, if the bulb does not glow, then there could be these possible reasons:

1. The cell is already used, this can also be a reason for the bulb not glowing.

2. This can also happen due to a loose circuit connection.

3. Maybe the bull is already fused.

4. It may be that some wire in the circuit is already broken from somewhere.
