(b) The resistor in the circuit of Figure 1 has a value of 12 and is connected to a 22 mF capacitor. The capacitor dielectric has infinite resistance, and the device is storing 891 m.J of energy just prior to t = 0. i. Write an expression for v(t) valid for t >0. ii. Compute the energy remaining in the capacitor at t = 11 ms and 33 ms. [2] [2] iii. If it is determined that the capacitor dielectric is much leakier than expected, having a resistance as low as 100 k2, repeat parts (a) and (b).
