When a capacitor is either charged or discharged through resistance, it requires a specific amount of time to get fully charged or fully discharged. That’s the reason, voltages found across a capacitor do not change immediately (because charge requires a specific time for movement from one point to another point).
(Figure 4). 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.
Switch the switch to the opposite position and start the stop clock. the capacitor has fully discharged. Plot a graph of voltage against time for the discharging of the capacitor, and use it to determine the time constant of the capacitor.
As has been illustrated in figure 6.47. In figure (a), an uncharged capacitor has been illustrated, because the same number of free electrons exists on plates A and B. When a switch is closed, as has been shown in figure (b), then the source, moves electrons towards B via the circuit.
Figure 6.47; Charging a capacitor When a charged capacitor is dissociated from the DC charge, as has been shown in figure (d), then it remains charged for a very long period of time (depending on the leakage resistance), and one feels an intense shock if touched.
To discharge It completely, short it with a wire. Prepare the rest of the circuit and, remove this wire as one of the last operations. Make sure the switch is off and build the circuit as shown on the drawing. Remember to remove the wire that shorts the capacitor. Start the stopwatch and turn the switch on simultaneously.

Can we "use" a capacitor while simultaneously charging it?
If, by "while it is in use", you mean while the capacitor is discharging, i.e., energy is flowing out of the capacitor to some load, then the answer is no since, by definition, if a capacitor is charging, energy is flowing into the capacitor. Put another way, a capacitor cannot be both charging and discharging at the same time. Either, the ...

How to Quickly and Safely Charge Supercapacitors
provides a small trickle charge in the 100 mA range to slowly raise the pack cell voltage. Then the charger must charge at a low pre-charge current in the 100 mA to 800 mA range until the battery reaches 2.6-3.0 V typically (VBAT_LOWV). After those two stages, the CC and CV stages are the same for supercap charging as previously discussed.
How to Charge Supercapacitor Banks for Energy Storage
desired voltage at the top of the string. More capacitors in series means higher voltage of the SC string with less capacitance. For instance, consider the choice of using two strings of four 2.7V 10F capacitors versus one string of eight (in series) of the same capacitor. While the same total charge and energy can be stored,
Energy storage in capacitor banks
The charging of the capacitor bank depends on the amount of supply voltage and the duration of charging and discharging operation depends on the type of the load connected across it as shown in Fig. 4.16. Depending on the charging methods, the chargers are classified as; Constant voltage, constant current, constant power, and resonant charging.
What Causes the Charging Sound of a Capacitor?
