13. In the circuit shown in Fig.
(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?
(i) No, because the circuit connection does not compete with any bulb so, the flow of current is not possible.
(ii) If the switch is in one position then the circuit will make a closed loop or we can say the given circuit is complete therefore all three bulbs will glow at the same time.
