A series circuit has a DC voltage source (36 volts), a resistor (75 ohms), a capacitor (28 farads), and a switch. The capacitor is initially uncharged and the switch closes at t=0. Sketch the exponential current and capacitor voltage: i(t)=Aexp(-t/tau) +B, and Vc(t)=Dexp(-t/tau) +F. Find: A,B,D,F,tau,i(t=tau),i(t=4tau),Vc(t=tau),and Vc(t=3tau). ans:9
