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.
A battery stores electrical energy and releases it through chemical reactions, this means that it can be quickly charged but the discharge is slow. Unlike the battery, a capacitor is a circuit component that temporarily stores electrical energy through distributing charged particles on (generally two) plates to create a potential difference.
Capacitance and energy stored in a capacitor can be calculated or determined from a graph of charge against potential. Charge and discharge voltage and current graphs for capacitors. Capacitor charge and discharge graphs are exponential curves. in the above circuit it would be able to store more charge.
Charge and discharge voltage and current graphs for capacitors. Capacitor charge and discharge graphs are exponential curves. in the above circuit it would be able to store more charge. As a result, it would take longer to charge up to the supply voltage during charging and longer to lose all its charge when discharging.
This process will be continued until the potential difference across the 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 gradually decrease to zero.
