Consider the Circuit Shown in the Figure

question 28

Essay

Consider the circuit shown in the figure. The battery has emf ε = 25 volts and negligible internal resistance. The inductance is L = 0.80 H and the resistances are R₁ = 12 Ω and R₂ = 9.0 Ω. Initially the switch S is open and no currents flow. Then the switch is closed.
(a) What is the current in the resistor R₁ just after the switch is closed?
(b) After leaving the switch closed for a very long time, it is opened again. Just after it is opened, what is the current in R₁?
