AI Customer ServiceWhen the power supply is connected to the capacitor, there is an increase in flow of electric charge, called charging. When the power supply is removed from the capacitor, the discharging phase begins; and there is a constant reduction in the voltage between the two plates until it reaches zero. What is charging of a capacitor?
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.
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.
After 2 time constants, the capacitor discharges 86.3% of the supply voltage. After 3 time constants, the capacitor discharges 94.93% of the supply voltage. After 4 time constants, a capacitor discharges 98.12% of the supply voltage. After 5 time constants, the capacitor discharges 99.3% of the supply voltage.
Once the capacitor is charged in your circuit, no current will flow. If the capacitor is fully discharged, then the current at the start will be 100 V/8 Ω = 12.5 A, but since the power supply can only deliver 5 A you will only get 5 A during the charge phase. As the capacitor charges, the current flow will go to zero.
When the power supply is removed from the capacitor, the discharging phase begins. During discharging, there is a constant reduction in the voltage between the two plates until it reaches zero. How Do You Discharge a Capacitor Safely?
