Question

In the circuit attached, switch a has been closed for a long time and switch b has been open for a long time.

The switches move simultaneously and instantaneously at t = 0.  

The values for each of the circuit parameters are:

Ia = 25 mA, Vb = 20 V, R1 = 100 ohm, R2 = 25 ohm, R3 = 130 ohm, R4 = 200 ohm, R5 = 300 ohm, C = 20 mF

Part A) Find Vc(0+)

Part B) Find Vc(t --> infinity)

Part C) Find the time constant for the circuit for t >= 0+

Part D) Find the equation for Vc(t) for t >= 0+

Part E) Find the equation for the current through the capacitor ic(t) for t >= 0+
