Current in B1 will promptly become zero while current in B2 will slowly tend to zero.

Q. The adjoining figure shows two bulbs $B_{1}$ and $B_{2}$ resistor $R$ and an inductor $L .$ When the switch $S$ is turned off,

Both $B_{1}$ and $B_{2}$ die out promptly

Both $B_{1}$ and $B_{2}$ die out with some delay

$B_{1}$ dies out promptly but $B_{2}$ with some delay

$B_{2}$ dies out promptly but $B_{1}$ with some delay

Current in $B_{1}$ will promptly become zero while current in $B_{2}$ will slowly tend to zero.

Q. The adjoining figure shows two bulbs B1​ and B2​ resistor R and an inductor L. When the switch S is turned off,

Both B1​ and B2​ die out promptly

Both B1​ and B2​ die out with some delay

B1​ dies out promptly but B2​ with some delay

B2​ dies out promptly but B1​ with some delay
