Question 14

Q13) In the circuit shown in Fig. 14.25

(i) Would any of the bulbs glow when the switch is in the ‘OFF’ position?

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

Solution:

(i) No, none of the bulbs will glow when the switch is in the ‘OFF’ position because the current will not flow through the circuit.

(ii) When the switch is turned to the ‘ON’ position, then all the bulbs will glow at once because they all are connected to the same battery and switch in the same circuit.
