प्रश्न
Will the bulb glow in the circuit shown in Fig. 12.6? Explain.
उत्तर
No, the bulb will not glow in this circuit because the switch is open and the circuit is incomplete. Current flows only in a closed circuit.

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.
