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.
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. In this way, the flow of electrons starts from plate A, and electrons start to store on plate B.
Charging and Discharging of Capacitor with Examples- When a capacitor is connected to a DC source, it gets charged. 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.
Once the charges even out or are neutralized the electric field will cease to exist. Therefore the current stops running. In the example where the charged capacitor is connected to a light bulb you can see the electric field is large in the beginning but decreases over time.

5.19: Charging a Capacitor Through a Resistor
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 ...
