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.
When 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?
Charging a capacitor is very simple. A capacitor is charged by connecting it to a DC voltage source. This may be a battery or a DC power supply. Once the capacitor is connected to the DC voltage source, it will charge up to the voltage that the DC voltage source is outputting.
A capacitor consists of two parallel conducting plates separated by an insulator. When it is connected to a voltage supply charge flows onto the capacitor plates until the potential difference across them is the same as that of the supply. The charge flow and the final charge on each plate is shown in the diagram.
Charging refers to the situation where there is an increase in potential difference while both conducting plates get an equal and opposite charge. The capacitor is fully charged when the voltage of the power supply is equal to that at the capacitor terminals. How do you calculate the charge and discharge of a capacitor?
