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.
Consider a circuit having a capacitance C and a resistance R which are joined in series with a battery of emf ε through a Morse key K, as shown in the figure. When the key is pressed, the capacitor begins to store charge. If at any time during charging, I is the current through the circuit and Q is the charge on the capacitor, then
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 current will become zero.
The main purpose of having a capacitor in a circuit is to store electric charge. For intro physics you can almost think of them as a battery. Edited by ROHAN NANDAKUMAR (SPRING 2021) Charging a Capacitor Charging a capacitor isn’t much more difficult than discharging and the same principles still apply.
Charging and Discharging: The capacitor charges when connected to a voltage source and discharges through a load when the source is removed. Capacitor in a DC Circuit: In a DC circuit, a capacitor initially allows current flow but eventually stops it once fully charged.
When a wire is connected across a charged capacitor, as has been illustrated in fig. 6,49, the capacitor discharges. For doing so, a very low resistance path (i.e., wire) is connected to a switch parallel to the capacitor, as can be seen in fig. (b).
