Zubeda made an electric circuit using a cell holder, 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.

Possible reasons are as follows:
• The bulb may be fused or defective.
• Cells are not connected properly.
• There may be loose connections.
• The switch is not functioning well.
• The cells are dried up i.e. the power of the cell has been exhausted.
