Capacitor Charging. When a capacitor is connected to a power source, such as a battery, it begins to accumulate or ''store'' charge. This process is known as capacitor charging. The power source provides a potential difference across the capacitor''s plates, causing current to flow. This current then accumulates as electric charge on the plates.
When the plates are charging or discharging, charge is either accumulating on either sides of the plates (against their natural attractions to the opposite charge) or moving towards the plate of opposite charge. While …
