The time constant of a discharging capacitor is the time taken for the current, charge or potential difference to decrease to 37 \% of the original amount.
Capacitor Discharge Graph: The capacitor discharge graph shows the exponential decay of voltage and current over time, eventually reaching zero. What is Discharging a Capacitor? Discharging a capacitor means releasing the stored electrical charge. Let’s look at an example of how a capacitor discharges.
