Question

In the circuit shown in the figure below, ε = 66.0 V, R₁ = 46.0 Ω, R₂ = 31.0 Ω, and L = 0.300 H.

(a) Switch S is closed. At some time t afterward the current in the inductor is increasing at a rate of di/dt = 50.0 A/s. At this instant, what is the current i₁ through R₁ and the current i₂ through R₂?
i₁ = 1 A
i₂ = 2 A

(b) After the switch has been closed a long time, it is opened again. Just after it is opened, what is the current through R₁?
