In Fig, take E0 = 12 V, R1 = 4.0 W, R2 = 8.0 W, R3 = 2.0 W, and
L = 2.0 H. What is the current I2 (a) immediately after the switch
is first closed and (b) a long time after the switch is closed? (c)
After a long time the switch is again opened. Now what is I2?
The Problem with the picture is on Problem 36 in the website
