In the circuit shown, switch S is connected to position 2 for a long time and then joined to position 1. The total heat produced in resistance 
is
A
B
C
D
Text Solution
Verified by ExpertsThe correct answer is:
A
When the key is at position for a long time; the energy stored in the inductor is:
This whole energy will be dissipated in the form of heat when the inductor is connected to 
and no source is connected.
