A capacitor with an initial potential difference of 125 V is discharged through a resistor when a switch between them is closed at t = 0s. At t = 10.0 s, the potential difference across the capacitor is 1.56 V. (a) What is the time constant of the circuit? (b) What is the potential difference across the capacitor at t = 16.8 s?
