1.	In the circuit shown, the switch ‘S’ has been closed for a long time and then opens at t = 0. (a) Find the current through the inductor just before the switch is opened. (b) Find the current I a long time after the switch is opened. (c) Find current I as a function of time after the switch is opened. Also write the current through the cell as a function of time.
Answer» Correct Answer - (a) 6A (b) 44 (c) `I = 4 + 2e^(-5t)`, current through cell `= (21)/(4) + 2e^(-5t)`
