Higher Order Question
A student made a circuit by using an electric cell, a switch, a torch bulb (fitted in the bulb holder), and copper connecting wires. When he turned on the switch, the torch bulb did not glow at all. The student checked the circuit and found that all the wire connections were tight.
- What could be the possible reason for the torch bulb not glowing even when the circuit appears to be complete?

What are the essential components of an electric circuit?
Will the bulb glow in the circuit shown in the following figure? Explain.

Assertion: People struck by lightning receive a severe electrical shock.
Reason: Lightning carries very high voltage.
Set up the circuit shown in Figure again. Move the key to ‘ON’ position and watch carefully in which direction the compass needle gets deflected. Switch ‘OFF’ the current. Now keeping rest of the circuit intact, reverse the connections at the terminal of the cell. Again switch ‘on’ the current. Note the direction in which the needle gets deflected. Think of an explanation.
