Question

Explain all types of capacitors

Answer 1

Answer:

The different types of capacitors are following.

• Electrolytic Capacitor
• Mica Capacitor
• Paper Capacitor
• Film Capacitor
• Non-Polarized Capacitor
• Ceramic Capacitor

Explanation:

1. Electrolytic Capacitor = the electrolyte capacitors are used when the large capacitor values are required.
2. Mica Capacitor = This capacitor is a group of natural minerals and the silver mica capacitors use the dielectric. There are two types of mica capacitors which are clamped capacitors & silver mica capacitor.
3. Paper Capacitor = The construction of paper capacitor is between the two tin foil sheet and they are separated from the paper, or, oiled paper & thin waxed.
4. Film Capacitor = The film capacitors are also capacitors and they use a thin plastic as the dielectric.
5. Non-Polarized Capacitors = The nonpolarized capacitors are classified into two types plastic foil capacitor and the other one is the electrolytic nonpolarized capacitor.
6. Ceramic Capacitor = The ceramic capacitors are the capacitors and use the ceramic material as a dielectric.

1. Ceramic Capacitors
2. Film Capacitors
3. Power Film Capacitor
4. Electrolytic capacitor
5. Paper capacitor

Explain in Detail ;

1. Ceramic Capacitors

A ceramic capacitor is considered to be one of the most commonly used capacitors. The material used in this capacitor type is dielectric. Also, ceramic capacitors are a non-polar device which means that they could be used in any direction in the circuit.

2. Film Capacitors

Film capacitors are also known as a polymer film, plastic film, or film dielectric. The advantage of film capacitors is that they are inexpensive and come with limitless shelf life. The film capacitor uses a thin dielectric material with the other side of the capacitor metalized. Depending on the application, the film capacitor is rolled into thin films. The general voltage range of these capacitors is from 50 V to 2 kV.

3. Powers Film Capacitors

Construction techniques and materials that are used in power film capacitors are similar to that of ordinary film capacitors. Polypropylene film is used as a dielectric in a capacitor.

4. Electrolytic Capacitors

In an electrolytic capacitor metallic anode coated with an oxidized layer used as a dielectric. These capacitors are polarized. Electrolytic capacitors are categorized based on their dielectric.

• Aluminum electrolytic capacitors – aluminum oxide (dielectric).
• Tantalum electrolytic capacitors – tantalum pentoxide (dielectric).
• Niobium electrolytic capacitors – niobium pentoxide (dielectric).

5. Paper Capacitor

Paper capacitor is also known as a fixed capacitor in which paper is used as the dielectric material. The amount of electric charge stored by the paper capacitor is fixed. It consists of two metallic plates and paper which is used as a dielectric material is placed between these plates.
