Distinguish between dielectrics and insulators
Dielectrics
|
Insulators
|
1. The materials, which are used to prevent the loss of electricity through certain parts of an electrical system, are known as dielectrics.
|
1. Insulators or insulating materials are the substances that retard the flow of heat or electricity or sound through them.
|
2. The main function is storage of electrical charge.
|
2. The main function of such materials is that of insulation.
|
3. All dielectrics are insulators because they avoid the flow of electric current through them.
|
3. All insulators are not dielectrics because they can not store charges like dielectrics.
|
4. They have electrical conductivity less than 10-6 mohs/cm
|
4. They are bad conductors of electricity
|
5. Examples- Air, N2 gas , CO2 gas, Silicon fluid etc
|
5. Examples-Rubber, Plastics etc.
