The Capacitor Discharge Calculator calculates the voltage that a capacitor with a capacitance, of C, and a resistor, R, in series with it, will discharge to after time, t, has elapsed. Enter inntial voltage, time, resistance, capacitance and choose applicable prefixes.
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.
Voltage at time ‘t’ while discharging: The time constant, RC, is the time it takes for the voltage across the capacitor to charge or discharge 63.2%, which is equal to e-1. The amount of electric charge that has accumulated on the plates of the capacitor can be calculated if the voltage and capacitance are known.
The discharge of a capacitor can occur spontaneously when it is not connected to a power source, or on command when it is connected to a discharge circuit. In this article, we will look at the discharge time of the capacitor and the voltage across the capacitor during the discharge process.
Capacitor discharge time refers to the period it takes for a capacitor to release its stored energy and decrease its voltage from an initial level (V) to a specific lower level (Vo), typically to either a negligible voltage or to a fraction of the initial voltage.
The formula for calculating the voltage across the capacitor as a function of time is as follows: Uc = Ee^ (-t/RC), where Uc is the voltage across the capacitor, E is the initial voltage across the capacitor, t is the discharge time of the capacitor, R is the circuit resistance, C is the capacitance of the capacitor.
