प्रश्न
Zubeda made an electric circuit using a cell holder shown in Figure, a switch and a bulb. When she put the switch in the ‘ON’ position, the bulb did not glow. Help Zubeda in identifying the possible defects in the circuit.

उत्तर
- 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, the circuit will not be complete, and current will not flow through it. Hence, the bulb will not glow. it is important to connect the cells in the right series.
- The positive terminal of the first cell should be connected with the negative terminal of the second cell.
- The switch should be closed properly, and the bulb should not be fused. If Zubeda checks these, then the bulb will certainly glow.
