WebUsing the Capacitor Discharge Equation The time constant is used in the exponential decay equations for the current, charge or potential difference (p.d) for a capacitor discharging through a resistor; These can be used to determine the amount of current, charge or p.d left after a certain amount of time when a capacitor is discharging Web5. You can derive it from the charge equation for a capacitor: Q=C*V. Rearranging it you have. V=Q/C. Since some of the values will be changing over time we have to express this equation in terms of time: V (t) = Q (t) / C (t) C (t) is a constant - capacitance never changes, so the equation can be simplified: V (t) = Q (t) / C.
