A capacitor with an initial potential difference of 144 V is discharged through a resistor when a switch between them is closed at t = 0 s. At t = 10.0 s, the potential difference across the capacitor is 1.05 V.
(a) What is the time constant of the circuit?
(b) What is the potential difference (in V) across the capacitor at t = 16.7 s?
