Question

three bulbs X Y and Z are comnected in a circuit as shown in the figure. when the switch is put on then which ine will glow first

Answer 1

All three bulbs will glow at the same time. No matter the orientation of the bulbs, electric current will flow equally along the circuit.

But if talking about split-second glowing, the bulb Z will glow first because it is near the battery.

But the one and true answer is the first case.
