Question:

Suppose that the resistance in the circuit of Figure 8.4. l(a) is 3 x l06 Ω. A voltage is applied to the circuit and then is suddenly removed at time t = 0. The measured voltage across the capacitor is given in the following table. Use the data to estimate the value of the capacitance C.
Time t (s)Voltage vc (V)
