This current is drawn by the capacitor and we call it a “charging current”. The capacitor is starting to “charge up” as long as the DC voltage source is applied. As soon as the voltage is reduced, the capacitor starts to do “discharging” with the direction opposite to the voltage source. You may wonder “why is it like that?”.
The charging current asymptotically approaches zero as the capacitor becomes charged up to the battery voltage. Charging the capacitor stores energy in the electric field between the capacitor plates. The rate of charging is typically described in terms of a time constant RC. C = μF, RC = s = time constant. just after the switch is closed.
Capacitor Charging Definition: Charging a capacitor means connecting it to a voltage source, causing its voltage to rise until it matches the source voltage. Initial Current: When first connected, the current is determined by the source voltage and the resistor (V/R).
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.
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. When the switch S is closed, the capacitor starts charging, i.e. a charging current starts flowing through the circuit.
The capacitor will be charged about 99.995% of the voltage source. What happens when a capacitor is fully charged? The capacitor will stop charging if the capacitor is “fully-charged”.
