Capacitors

A capacitor is a passive two-terminal electrical component that stores potential energy in an electric field. The effect of a capacitor is known as capacitance. While some capacitance exists between any two electrical conductors in proximity in a circuit, a capacitor is a component designed to add capacitance to a circuit.

More capacitance requires a larger capacitor. Plates with more overlapping surface area provide more capacitance, while more distance between the plates means less capacitance.

The material of the dielectric even has an effect . In a way, a capacitor is a little like a battery. Although they work in completely different ways, capacitors and batteries both store electrical energy. If you have read How Batteries Work, then you know that a battery has two terminals. Inside the battery, chemical reactions produce electrons on one terminal and absorb . A basic overview of capacitors and capacitance.

Introduction to the capacitance of a two plate capacitor. A simple explanation of how capacitors store electricity and the different jobs they do in electronic circuits.

The capacitor is made of close conductors (usually plates) that are separated by a dielectric material. The plates accumulate electric charge when connected to power source. One plate accumulates positive charge and the other plate accumulates negative . This definition explains what a capacitor is and how it works.

We have fixed and variable capacitors , networks and arrays and more in-stock and ready to ship today.

Working voltage: Since capacitors are nothing more than two conductors separated by an insulator (the dielectric), you must pay attention to the maximum voltage allowed across it.

If a circuit is driven by a battery, the battery will charge capacitors until the voltage across the capacitor perfectly opposes the voltage from the battery, resulting in an effective open circuit in .
