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.
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.
To increase the rate of discharge, the resistance of the circuit should be reduced. This would be represented by a steeper gradient on the decay curve. The time constant of a discharging capacitor is the time taken for the current, charge or potential difference to decrease to 37 \% of the original amount.
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.
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.
The time constant of a discharging capacitor is the time taken for the current, charge or potential difference to decrease to 37 \% of the original amount. It can also be calculated for a charging capacitor to reach 63 \% of its maximum charge or potential difference.
