Consider the LR circuit. We have R1=19 Ohms, R2=23 Ohms, R3=23 Ohms, V=14 Volts, L=0.09 H.

L and R2 are connected in series, Combination of L and R2 in series is connected with R3 in parallel. This whole combination is connected in series with R1 and voltage source and switch.

At t=0 the switch is closed.
(a)Immediately after the switch is closed, what are currents I1, I2, I3 ?

(b)What are I1, I2, I3 after the switch has been closed for a long time?

The switch is now opened again.
(c) What are the I1, I2, I3 currents after the switch is reopened?
