Suppose that at t=0, we connect an uncharged 10{μF capacitor to a charging circuitconsisting of a 2500-V voltage source in series with a 2{MΩ resistance. At t=40s, the capacitoris disconnected from the charging circuit and connected in parallel with a 5{MΩ resistor.Determine the voltage across the capacitor at t=40 s and at t=100 s. (Hint: You may find itconvenient to redefine the time variable to be t′=t−40 for the discharge interval so that thedischarge starts at t′=0.)

For the circuit, now keep switch J2 closed, close switch J1. Determine the expressions for the voltage across the capacitor and the current delivered by the source.

In the figure below, the switch is open for a long time and the switch is closed at t = 0 .a) Find the initial conditions for t = 0? (Vc(0)=?,iL(0)=?)b) Find for the inductor current for t >=0 ?(iL(t)=?)c) Find the capacitor voltage and current through the switch (isw) for t >=0 ? (Vc(t)=?)
