(choose chapter or problem)

After time t = 0, a given circuit is represented by the circuit diagram shown in Figure P 8.3-28.

(a) Suppose that the inductor current is

                                           \(i(t)=21.6+28.4 e^{-4 t} \mathrm{~mA} \text { for } t \geq 0\)

Determine the values of \(R_1\) and \(R_3\).

(b) Suppose instead that \(R_1=16 \Omega, R_3=20 \Omega\), and the initial condition is i(0) = 10 mA.

Determine the inductor current for \(t \geq 0\).
