Problem 1 (11 points): Consider the circuit shown below and assume that the switch has been closed for a long time. Then, at t = 0^sec, the switch opens. (a) Draw the equivalent circuit for t 0 and from that, Calculate v(infinite). (3 points) (c) Find the time constant of the circuit for t > 0. (2 points) (d) Finally, for t > 0, determine the voltage across the capacitor, i.e., v(t). (2 points)
