Question
Switch S is closed for a long time at t = 0. It is opened, then:
- total heat produced in resistor R after opening the switch is
- total heat produced in resistor R1 after opening the switch is
- heat produced in resistor R1 after opening the switch is
- no heat will be produced in
The correct answer is: heat produced in resistor R1 after opening the switch is
Just before opening the switch, the current in the inductor is 
. Energy stored in it=
This energy will dissipate in the resistors and 
in the ratio

Electrical resistance of certain materials, known as superconductors, changes abruptly from a nonzero value to zero as their temperature is lowered below a critical temperature
