When charging a capacitor, the direction of charge flow is from the power source (positive terminal) to the positive plate of the capacitor. This causes the positive plate to accumulate positive charge, while the negative plate accumulates negative charge.
When discharging a capacitor, the direction of charge flow is reversed. The stored charge begins to move from the positive plate to the negative plate, resulting in the discharge of the capacitor's energy.
The evidence for this can be explained using the concept called electric current. Electric current is the flow of electric charge, and it is conventionally defined as the direction of flow of positive charges. In reality, electrons are the charge carriers in most materials, and they move in the opposite direction to the conventional current flow.
During charging, the electric current from the power source provides an excess of positive charge, which moves across the circuit and accumulates on the positive plate of the capacitor. This establishes a potential difference across the capacitor, causing it to charge.
During discharging, the excess positive charge on the positive plate begins to flow toward the negative plate. Since electrons are negatively charged, they move in the opposite direction of the current. This results in the discharge of the capacitor's stored energy.
Experimental evidence for this can be observed through circuit analysis and measurement of voltage and current in the circuit while charging and discharging the capacitor.
