The word capacitance is derived from capacity, capacity is to contain, or store. Unlike the storage of water which can be stored in ponds, lakes, tanks and our seas which are our almost unlimited reservoir of water we have very limited options for direct storage of electrical energy. As a matter of fact, we have only one option as a battery to store electrical energy in the form of chemical energy and is not a direct method.

## How Does A Capacitor Work?

The time it takes to discharge a capacitor is usually only a split second. And so is the time to recharge it. So the capacitor can store charge. And it can release the charge when needed. But how does it do this? A capacitor is made up of two metallic plates. With a dielectric material in between the plates.

Whenever an electric voltage exists between two separated conductors, an electric field is present within the space between those conductors. In basic electronics, we study the interactions of voltage, current, and resistance as they pertain to circuits, which are conductive paths through which electrons may travel. Despite its abstract nature, almost every one of us has direct experience with fields, at least in the form of magnets. Have you ever played with a pair of magnets, noticing how they attract or repel each other depending on their relative orientation? Physicists describe the interaction of magnets in terms of magnetic fields in the space between them. If iron filings are placed near a magnet, they orient themselves along the lines of the field, visually indicating its presence.

## Electric Fields and Capacitance

A capacitor is a device that stores electrical energy in an electric field. It is a passive electronic component with two terminals. 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. The capacitor was originally known as a condenser or condensator. The physical form and construction of practical capacitors vary widely and many types of capacitor are in common use.

Just like the various electrical and electronic components such as resistor, transistor, ICs, the capacitor is one of the most used components in electrical and electronic circuit design. Sometimes capacitor is referred as a condenser. It plays a vital role in various embedded applications. These components are obtainable at different ratings. It comprises of two metal plates that are parted by a dielectric or a non conducting substance. There are various kinds of capacitors are available in the market , but the difference between these capacitors are normally made with the dielectric material used in the plates. Some capacitors look like tubes, some capacitors are designed with ceramic materials and dipped into an epoxy resin to cover them.

## What is Capacitor and How Does It Work ? – Physics and Applications

What is Resistor and Its Function? Warm hints: This article contains about words and reading time is about 15 min. In electronic circuits, capacitors are used to block DC through AC, as well as to store and discharge charge to act as a filter to smooth out the output ripple signal.

Мидж злорадно подмигнула. - Никогда не забывай, Чед, что Большой Брат знает. Большой Брат.

На противоположной стене висело распятие в натуральную величину. Беккер остановился. Тупик. Стоя возле креста, он слушал, как приближаются шаги Халохота, смотрел на распятие и проклинал судьбу. Слева послышался звон разбитого стекла.

Capacitors are the most widely used electronic components after resistors.

Although capacitors operate in the same way whatever the capacitor application or use, there are several different uses for capacitors in circuits.
