Customer ServiceRC Circuits. An (RC) circuit is one containing a resisto r (R) and capacitor (C). The capacitor is an electrical component that stores electric charge. Figure shows a simple (RC) circuit that employs a DC (direct current) voltage source. The capacitor is initially uncharged. As soon as the switch is closed, current flows to and from the initially uncharged capacitor.

A discharging and charging of a capacitor example is a capacitor in a photoflash unit that stores energy and releases it swiftly during the flash. Timing Circuit is the most important and useful advantage of a capacitor’s charging-discharging characteristics.
In a circuit, capacitors and resistors are frequently seen together. In real life, such RC circuits are common. They are employed in camera flashes and heart pacemakers; to control the speed of a car’s windshield wipers and the timing of traffic signals, and a variety of other electrical equipment.
As time progresses, the capacitor charges up, and a potential difference develops across the capacitor. Let us consider at any time “t”, the charge across the capacitor is “q”, and the current in the circuit is “i”. The potential difference across the capacitor is q/C, and the potential difference across the resistor is iR.
The charging and discharging of the capacitor is not an instant process but takes some time. If the resistor and capacitor are connected in series, the capacitor charges gradually through the resistor until the voltage across the resistor is equal to the supply voltage.
