Figure shows two bulbs B₁ and B₂, resistor R and an inductor L. When the switch S is turned off,

Answer & explanation

Correct answer: option 3

Here the bulb B₁ will die out promptly but B₂ with some delay. The reason is that the branch of bulb B₂ contains inductance. Due to the effect in inductance, the current in this branch continues to flow for sometime even the switch S is turned off.
