A coil of inductance 10H resistance 
is connected as shown in figure. After the switch S has been in connected with point 1 for a very long time, it is moved to point 2 at t=0
For the value of R obtained in (a), the time taken for 95% of the stored energy dissipated is close to
0.10 sec
0.15 sec
0.50 sec
1.0 sec
Explanation:
For t > 0, the circuit in Laplace Domain can be represented as shown below,
Inductor Voltage Source, 
Initial stored energy in inductor
If 95% energy is dissipated in Inductor only 5% energy remains
Remaining energy in inductor
