A capacitor with capacitance C=100μF is connected in series with a resistor of resistance R=1MΩ. If the capacitor is initially (t=0s) charged with a potential difference of ε=20V across its plates, how much time will pass before the potential difference drops by 25% to V=15V (assuming the capacitor is disconnected from power) ?
