The current source shown in the circuit of Fig. P4.19 is given by the displayed waveform. Determine vout(t) for t ā„ 0 given that R1 = 1 Ģ, R2 = 0.5 Ģ, and L = 0.5 H. L = 0.5 H + vout(t) R1 R2 is(t) 1.5 A Ģ = 4 rad/s 1 A 0.5 A Figure P4.19: Circuit for Problem 4.19 and current waveform for Problems 4.19 and 4.20
