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.
In this article, you will learn about charging and discharging a capacitor. When a voltage is applied on a capacitor it puts a charge in the capacitor. This charge gets accumulated between the metal plates of the capacitor. The accumulation of charge results in a buildup of potential difference across the capacitor plates.
The negative plate repels electrons, which are attracted to the positive plate through the wire until the positive and negative charges are neutralized. Then there is no net charge. The capacitor is completely discharged, the voltage across it equals zero, and there is no discharge current. Now the capacitor is in the same uncharged condition.
The accumulation of charge results in a buildup of potential difference across the capacitor plates. So there is a voltage built across the capacitor. When the capacitor voltage equals the applied voltage, there is no more charging. The charge remains in the capacitor, with or without the applied voltage connected.
energy dissipated in charging a capacitorSome energy is s ent by the source in charging a capacitor. A part of it is dissipated in the circuit and the rema ning energy is stored up in the capacitor.

The same ideas also apply to charging the capacitor. During charging electrons flow from the negative terminal of the power supply to one plate of the capacitor and from the other plate to the positive terminal of the power supply.

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. This discharge process is important in various electronic circuits, including timing circuits, filters, and power supply systems.
Charging a capacitor isn''t much more difficult than discharging and the same principles still apply. The circuit consists of two batteries, a light bulb, and a capacitor. Essentially, the electron current from the batteries will continue to run until the circuit reaches equilibrium (the capacitor is "full").

However, a potential hazard of capacitors is their ability to retain charge for extended periods, even after power is disconnected. Accidentally touching the leads of a charged capacitor can result in anything from a mild shock to severe electric shock, burns, or even fires in high-capacitance scenarios. Therefore, understanding how to safely discharge a capacitor is …

So, if you planning to work with capacitors, you better discharge them properly even after disconnecting the power supply. Capacitors in large AC / DC Power Supplies are very big and can hold the charge for days or months if not discharged. If you are salvaging parts from such old devices, don''t assume there won''t be any danger.
As more charge is stored on the capacitor, so the gradient (and therefore the current) drops, until the capacitor is fully charged and the gradient is zero. As the capacitor discharges (Figure 3(b)), the amount of charge is initially at a maximum, as is the gradient (or current).

No, capacitors cannot charge and discharge instantly. Charging and discharging a capacitor require a finite amount of time. The time it takes for a capacitor to charge or discharge depends on the circuit''s characteristics, including the resistance and capacitance values, as well as the applied voltage or current. 19.
