# Formula: Discharging Capacitor Voltage    Anfangsspannung    Capacitance    Electrical Resistance    Time

## Voltage

Unit
This is the voltage measured across the capacitor (e.g. between the two capacitor plates). When the capacitor is discharged, the voltage decreases exponentially with time $$t$$. At the end of the discharge process, it reaches approximately zero.

## Anfangsspannung

Unit
Elektrische Spannung auf dem Kondensator vor dem Entladen. Also die Spannung zum Zeitpunkt $$t = 0$$.

## Capacitance

Unit
Electrical capacitance is a characteristic quantity of the capacitor and tells how many charges must be brought onto the capacitor to charge the capacitor to the voltage $$1 \, \text{V}$$. Together with the resistance $$R$$, the capacitance determines how fast the capacitor discharges.

## Electrical Resistance

Unit
Resistor with the resistance $$R$$ connected in series with the capacitor. The Resistance has an influence on how fast the capacitor can discharge.

## Time

Unit
The capacitor, with the source voltage $$U_0$$, is now discharged by short-circuiting the capacitor. The discharge process happens with a time delay (exponential decay of $$U_{\text C}(t)$$).
