Rahul wants to make an electric circuit. He has a bulb, two wires, a safety pin, and a piece of copper. He does not have any electric cell or battery. Suddenly he gets some idea. He uses lemon instead of a battery and makes a circuit. Will the bulb glow?
Study the electric circuit below. Which of the following switches should be closed so that only two bulbs will light up

In a circuit, if the key is in open (off) condition, then electricity will not flow.
Observe the circuit given:
1. Would any of the bulbs glow when the switch is in the ‘OFF’ position?

2. What will be the order in which the bulbs A, B, and C will glow when the switch is moved to the ‘ON’ position?
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.
