Capacitors are widely used as parts of electrical circuits in many common electrical devices. Unlike a resistor, an ideal capacitor does not dissipate energy, although real-life capacitors do dissipate a small amount (see Non-ideal behavior).
In this chapter we introduce capacitors, which are one of the simplest circuit elements. Capacitors are charge-storing devices that can store energy in the form of an electric potential energy, and are commonly used in a variety of electric circuits. These keywords were added by machine and not by the authors.
They can also be used in charge pump circuits as the energy storage element in the generation of higher voltages than the input voltage. Capacitors are connected in parallel with the DC power circuits of most electronic devices to smooth current fluctuations for signal or control circuits.
Today, capacitors are widely used in electronic circuits for blocking direct current while allowing alternating current to pass. In analog filter networks, they smooth the output of power supplies. In resonant circuits they tune radios to particular frequencies. In electric power transmission systems, they stabilize voltage and power flow.
Capacitors are connected in parallel with the power circuits of most electronic devices and larger systems (such as factories) to shunt away and conceal current fluctuations from the primary power source to provide a "clean" power supply for signal or control circuits.
You can see why capacitors are considered one of the fundamental components of electrical circuits. Lichtenberg figures, named for the German physicist Georg Christof Lichtenberg (1742–1799), are tree-like branch patterns with the “branches” are created by the dielectric breakdown produced by a strong electric field.
