Originally recognized as a condenser, a capacitor is an electrical component, which preserves energy in an electric field. The capacitor only stores the electrons, but can’t produce them. It is comprised 2 electrical conductors separated by a dielectric, known as insulator. The conductors, the metal plates, when attached to power source build up electric charge. The two plates mount up positive as well as negative charge. The amount of electric charge stored or preserved in the capacitor at 1 volt is the capacitance.
In other words, a capacitor is characterized by the parameter capacitance. It is measured in units of F (Farad).Capacitors are of different types depending on the purpose. The capacitors that are being used widely include electrolytic, ceramic, mica, mylar and the likes.
How does it Work?
The capacitor is used for different applications depending on its types and sizes of dielectric used. There are capacitors that can be used for low voltage as well as high voltage applications. For example, tuning circuit air is extensively used as the dielectric in radio applications. For applications in timer, the dielectric is the circuit mylar. Glass is usually used for high voltage applications. For MRI and X-ray machine applications, ceramic is normally preferred.
In a capacitor, the dielectric material plays an integral part in storing and preserving the electrical energy.
Advantages of Capacitors:
Capacitors kits have a number of advantages as they can discharge within a fraction of a second. They are used in various applications that need high speed usage, such as in laser techniques and camera flash. In these applications, capacitors need to function quickly and they are capable of that. Capacitors come very handy in removing ripples by exterminating the peaks and filling in the valleys. They are further used in ACs as they allow the ac voltage to pass through and block dc voltage.
