vollage drops across R₁, R₂, and R, and the inductance Lare denoted as V₁, V₂, V and V, respectively.

Suppose that initially there is no current in the inductor, and the switch is open

(1) Close the switch, and find 1₁. ₂. ₂. and Vimmediately after the switch is closed.

(1) After the switch is closed for a very long time, find I₁, I₂, l, and V₁.

(The switch is then reopened. Find 1, I₂, I₂, and V. Immediately after the switch is reopened

(v) After the switch is reopened for a very long time, find ₁. ₂. I₂. and V₁
