Question

Rohan has three bulbs A, B and C. He connected the
positive terminal of the battery with Cand
negative with A. He then connected the bulb B
and a switch in between A and C He wants
to see in what sequence the bulbs will glow
when the switch is turned ON.
​

Answer 1

In circuit, bulbs B and C are parallel with each other and bulb A is in series with this combination. If bulb C is fused then bulb A will glow less brightly because current flowing is decreased but bulb B will glow a bit more brightly as the voltage is increased.
