For t ≥ 0 the zero-input response of the circuit in Figure P7-35 is vC(t) = 20e-10kt V.
(a) Find C and iC(t) when R = 10 kΩ.
(b) Find the energy stored in the capacitor at t = 2 ms.
(c) Suppose the only capacitor you had available has a value of 0:022 μF. Could you achieve the same output by selecting a different R? How would the current change?
