6–19 A 33-μF capacitor and a 10-mH inductor are connected in parallel with a closed switch as shown in Figure P6–19. The inductor has – 5mA flowing through it at t = 0– . The switch opens at t = 0:

(a) Find the initial voltage across the capacitor at t = 0.

(b) Write an equation for the voltage across the elements for t > 0. Do not solve it.

(c) Simulate the circuit using Multisim. Connect an inductor in parallel with a capacitor and assign the appropriate initial conditions and run a transient analysis. Plot the voltage across the elements for 5 ms.

(d) Characterize the response signal.
