When a capacitor is charging, the way the charge Q and potential difference V increases stills shows exponential decay. Over time, they continue to increase but at a slower rate; This means the equation for Q for a charging capacitor is:; Where: Q = charge on the capacitor plates (C); Q 0 = maximum charge stored on capacitor when fully charged (C); e = the exponential function

while a capacitor is either charging or discharging. Capacitors are also referred to as condensers. The value of the capacitor is determined by 3 physical factors: the amount of surface area of the parallel metallic plates (A); the separation or distance between the plates (d) and the insulating material or dielectric between the plates.
As discussed earlier, the charging of a capacitor is the process of storing energy in the form electrostatic charge in the dielectric medium of the capacitor. Consider an uncharged capacitor having a capacitance of C farad. This capacitor is connected to a dc voltage source of V volts through a resistor R and a switch S as shown in Figure-1.
Likewise, as the current flowing out of the capacitor, discharging it, the potential difference between the two plates decreases and the electrostatic field decreases as the energy moves out of the plates. The property of a capacitor to store charge on its plates in the form of an electrostatic field is called the Capacitance of the capacitor ...

It can be manipulated to give predictions about measurable quantities by first solving it for the charge on the capacitor and then
The larger the time constant, the more time it takes to charge or discharge, and vice-versa. ... When a capacitor is discharging (when there is no battery linked to it), it almost acts like a battery. It will start giving off its energy (which is limited, unlike a battery).
Charging a Capacitor. When a battery is connected to a series resistor and capacitor, the initial current is high as the battery transports charge from one plate of the capacitor to the other. …
The students know that the electrical component "capacitor" can store electrical energy. The first experiment concentrates on the change in the capacitor voltage over time during charging and discharging. Qualitative statements are first derived, then the change in the voltage during charging and discharging is quantitatively determined.
However, there is a flow of charge through the source circuit. If the condition is maintained sufficiently long, the current through the source circuit ceases. If a time-varying voltage is applied across the leads of the capacitor, the source experiences an ongoing current due to the charging and discharging cycles of the capacitor.
