Consider the circuit shown in Figure.The circuit has been operating for a long time with the switch closed prior to t = 0.
a. Determine the values of iL, i1, i2, i3, and vC just before the switch opens.
b. Determine the values of iL, i1, i2, i3, and vC immediately after the switch opens.
c. Find iL(t) for t > 0.
d. Find vC(t) for t > 0.
