The adjoining figure shows two bulbs `B_(1)` and `B_(2)` resistor `R` and an inductor and `L`. When the switch `S` is turned off

Options

A. `B_(1)` dies out immediately but `B_(2)` will with some delay
B. `B_(2)` dies out immediately but `B_(1)` with some delay
C. Both `B_(1)` and `B_(2)` will die out immediately
D. Both `B_(1)` and `B_(2)` will die out with some delay

Answer

A

Explanation

R is connected in series with `B_(1)`.
`:.` Current in `B_(1)` become zero immediately. But L is connected in series with `B_(2)`. The decay of current in L is expnential hence `B_(2)` stops glowing after some time (a) is correct.
