The voltage across a discharging capacitor decreases exponentially over time, described by the formula: \ [ V (t) = V_0 \cdot e^ {-\frac {t} {RC}} \] where: \ (e\) is the base of the natural logarithm (approximately 2.71828).
The 3 variables which affect how the inital voltage discharges is time, t, the resistance of the resistor, R, and the capacitance of the capacitor, C. The greater the amount of time has elapsed, the more the capacitor will discharge. The less time that has elapsed, the less time the capacitor has to discharge.
The capacitor is discharged approx. 99.33% after a period of 5 τ. This means that at specified times, well over 5 τ the charging voltage is close to zero.

The voltage across the capacitor at any time ‘t’ while discharging can be determined using the calculator above. To do so, it requires the values of the resistor and capacitor, as well as the time ‘t’ at which we want to find the voltage.
