Solution

1) No.

When the switch is in ‘OFF’ position, the current does not flow through the circuit. Hence, none of the bulbs will glow.

2) Bulbs will glow simultaneously.

When the switch is moved to the ‘ON’ position, then all the bulbs will glow at once. This is because they all are connected to the same battery and switch.
