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.
If a larger value of resistance were used with the same value of capacitance in the above circuit, then a smaller current would flow, therefore it would take longer for the capacitor to charge up and longer for it to discharge. When the capacitor is charged current flows on either side of the capacitor.

Charging of a Capacitor – Formula, Graph, and Example
When the switch S is closed, the capacitor starts charging, i.e. a charging current starts flowing through the circuit. This charging current is maximum at the instant of switching and decreases gradually with the increase in the voltage across the capacitor. Once the capacitor is charged to a voltage equal to the source voltage V, the charging ...

When the capacitor is fully charged, the current has dropped to zero, the potential difference across its plates is (V) (the EMF of the battery), and the energy stored in the capacitor (see Section 5.10) is [frac{1}{2}CV^2=frac{1}{2}QV.] But the energy lost by the battery is (QV). Let us hope that the remaining (frac{1}{2}QV) is heat ...
