The relationship between voltage and current when a capacitor is discharging

The relationship between voltage and current is closely related when a capacitor is discharging. The current in the discharge process of a capacitor is proportional to the rate of voltage change. Specifically, when a capacitor is discharged, the voltage at both ends is directly related to the rate o
