THE CAPACITOR

Hello steemians, today I will be discussing about the capacitor and it types regarding on our basic electronic components tutorials. So, ltes being.

What is a Capacitor?
A capacitor is a condenser used for storing electric charges. It consists of two metal plates separated by an insulator called dielectric.

Types Of Capacitor

1. Air Capacitor:
This type of capacitor consists of one set of fixed plates and another set of movable plates. They are mainly used in radio work where it is required to vary the capacitance.

2. MICA Capacitor:
They consist of either of alternate layers of mica and metal foil clamped tightly together or of thin films of Silvet sputtered on the two sides of the mica sheet. They are used in high frequency circuits when it is necessary to reduce to a minimum the loss in dielectric, e.g; in tuned circuits and filters.

3. Paper Capacitor:
The electrodes consist of metal foils inter leaved with paper impregnated with with wax or oil and rolled into a compact from.

4. Ceramic Capacitor:
The electrodes consist of metallic coating(usually silver) on the opposite faces of a thin disc or pates of ceramic material such as hydrous silicate if magnesia. They are used in high frequency circuits subject to wide variation of temperature. They have high stability and low loss.

5. Electrolytic Capacitor:
The electrolytic capacitor consists of two aluminum foils, on with an oxide film and one without, the foil being inter leaved with a mater such as paper saturated with a suitable electrolyte. They are used where a large value of capacitance could with a small physical size is required.
