|Please tel me how to solve it!|

|It is RL circuit, we use Vs=R + Inductor.|
|Priya said: (Nov 23, 2011)|
|Time constant for RL circuit is t = L/R
5 time time constants it will to reach its max value. t = 5*0.1063829ms = 532 us.

|How we had taken resistance value?|

|Time constant for LR circuit is t = L/R.
Now R=120+820 = 940R.
L = 100mH.
So t = L/R
To reach maximum i.e. 100% value; it will take 5 time constants,
5 Time constants.
T = 5*0.1063829ms = 532us.

|On which basis t is multiplied by 5. I didn't please solve this problem.|
|Balu said: (Apr 28, 2017)|
|Because the current will have reached 99.5% of the steady state value after 5 time constants.|

|At position 2 inductor is discharging.
Before coming to position 1 inductor is completely discharged.
Its general formula for complete charging of capacitor and inductor 5T.
