Question

After a constant current in the inductor is established, the switch is
opened. The remaining questions refer to the time period that follows the opening of the switch.
(a) Calculate how much time it takes for the current through R3 to reach approximately 37%
of its initial value.
(b) When the current through R3 reaches 37% of its initial value, what is the voltage across
the inductor?
(c) Sketch qualitative graphs of the inductor discharge, showing the variation of the current I3
through the resistor R3, the voltage V on the inductor, and the current I on the inductor. Make
sure to indicate the numerical values of the various quantities at t = 0.

I know there isnt values for much anything just the symbols... but leave you answers in terms of the symbols.

Any help and insight is greatly appreciated. Will Rate Lifesaver who comes up with the best answer!

Thanks.

In the circuit below, (a) Find the current through the inductor (Ii), the voltage across R2 (V2i) and the current through R3 (I3i) immediately after the switch is closed. (b) Find the current through the inductor (Qf), the voltage across R2 (V2f) and the current through R3 (I3f) a long time after the switch is closed. (c) Sketch graphs for the three quantities above as functions of time. (d) Sketch how total current provided by the battery depends on time.
