Question

anuj constructed an electrical circuit by connecting a cell,a bulb and a switch .He found that bulb was not glowing .indicate three possible reasons.give reasons

Answer 1

1)all three not connected to each other
2)switch not on
3)Bulb is fused
4)cell is used up

Answer 2

Answer:

One of the reasons may be that the rubber band used in the cell holder may not be tight enough to keep the two cells in contact with each other. If the cells are not in proper contact with each other, then the circuit will not be complete and current will not flow through the circuit. Hence, the bulb will not glow.

The other reason may be that the two cells are not connected properly. The negative terminal of one cell must be connected to the positive terminal of the other cell.
