The “make-before-break” switch shown in Fig. 8.90 has been in position a

since the first episode of “Jonny Quest” aired on television. It is moved to

position b, finally, at time t = 0. (a) Obtain expressions for i(t) and vC(t) valid

for all values of t. (b) Determine the energy remaining in the capacitor at

t = 33 μs.
