Capacitors discharge evenly

Capacitor Discharge Time Calculator (with Examples)

The discharge time of a capacitor is primarily governed by the RC time constant (often denoted as τ), where R is the resistance through which the capacitor discharges, and C is the capacitance. The time constant represents the time required for the voltage across the capacitor to decrease to about 36.8% (substitute t=RC in the equation e −t/RC .
