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.
The Capacitor discharging cycle that a capacitor goes through is the cycle, or period of time, it takes for a capacitor to discharge of its charge and voltage. In this article, we will go over this capacitor discharging cycle, including:
(Figure 4). As charge flows from one plate to the other through the resistor the charge is neutralised and so the current falls and the rate of decrease of potential difference also falls. Eventually the charge on the plates is zero and the current and potential difference are also zero - the capacitor is fully discharged.
Capacitors can still retain charge after power is removed which could cause an electric shock. These should be fully discharged and removed after a few minutes A student investigates the relationship between the potential difference and the time it takes to discharge a capacitor. They obtain the following results:
C affects the discharging process in that the greater the capacitance, the more charge a capacitor can hold, thus, the longer it takes to discharge, which leads to a greater voltage, V C. Conversely, a smaller capacitance value leads to a quicker discharge, since the capacitor can't hold as much charge, and thus, the lower V C at the end.
The Capacitor Discharge Equation is an equation which calculates the voltage which a capacitor discharges to after a certain time period has elapsed. Below is the Capacitor Discharge Equation: Below is a typical circuit for discharging a capacitor.
