Circuits with Resistance and Capacitance. An RC circuit is a circuit containing resistance and capacitance. As presented in Capacitance, the capacitor is an electrical component that stores electric charge, storing energy in an electric field.. Figure (PageIndex{1a}) shows a simple RC circuit that employs a dc (direct current) voltage source (ε), a resistor (R), a capacitor (C),
This process of depositing charge on the plates is referred to as charging the capacitor. For example, considering the circuit in Figure 8.2.13, we see a current source feeding a single capacitor. If we were to plot the capacitor''s voltage over time, we would see something like the graph of Figure 8.2.14 . Figure 8.2.13 : Capacitor with current source. Figure 8.2.14 :
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).

A capacitor is charged by passing an electric current through it, which causes the plates to start accumulating an electrostatic charge. Since the strength of the charging current is maximum when the capacitor plates are uncharged and gradually decreases exponentially until the capacitor is fully charged, the charging process is neither instantaneous nor linear.
