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.
capacitor is equal to the potential difference across the battery. Because the current changes throughout charging, the rate of flow of charge will not be linear.At the start, the current will be at its highest but will graduall decrease to zero. The following graphs summarise capacitor charge. The potential diffe
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.
The other factor which affects the rate of charge is the capacitance of the capacitor. A higher capacitance means that more charge can be stored, it will take longer for all this charge to flow to the capacitor. The time constant is the time it takes for the charge on a capacitor to decrease to (about 37%).
A capacitor can store the amount of charge necessary to provide a potential difference equal to the charging voltage. If 100 V were applied, the capacitor would charge to 100 V. The capacitor charges to the applied voltage because it takes on more charge when the capacitor voltage is less.
Because the current changes throughout charging, the rate of flow of charge will not be linear. At the start, the current will be at its highest but will gradually decrease to zero. The following graphs summarise capacitor charge. The potential difference and charge graphs look the same because they are proportional.
