The circuit in Figure P7–60 is in the zero state when the step function input is applied. If the input source is VA ¼

70 V and L ¼ 0.5 H, select values of R and C so that the circuit’s output vO(t) for t 0 is critically damped. Use MATLAB or OrCAD to show your result for vO(t) (Hint:

Find the inductor current first.)
