An RC circuit is a circuit with both a resistor (R) and a capacitor (C). They are a common element in electronic devices and play an important role in the transmission of electrical signals. RC circuits are used as audio filters, electronic timers, oscillators, and more in a wide range of electronics project.

RC 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.
From a lower-level perspective, charge pump circuits work on the basic principle that the voltage across a capacitor cannot change instantaneously. As defined by the capacitor I-V equation, in order for a capacitor to change its voltage instantaneously, it would require an infinite amount of current. [I_C = C frac {dV_C}{dt} ]

When labeling your components in a circuit each resistor will be R#, so in this circuit R1, R2, R3, and R4. R1 will typically be the resistor closest to the positive node. Your circuit should also have the nominal values of each component annotated on the schematic diagram. With Resistors, you can find this using the Resistor Color Codes.
