Question

In the circuit shown, initially the switch is in position 1 for a long time. Then the switch is shifted to position 2 for a long time. Find the total heat produced in `R_(2)`

Answer 1

Correct Answer - `(LE^(2))/(2R_(1)^(2))`
Energy stored in inductor will appear as heat.
`H=1/2LI^(2)=1/2L(E/R_(1))^(2)=(LE^(2))/(2R_(1)^(2))`
