explain conducter, semiconductor, insulator
Answers
Answer:
conductor
In physics and electrical engineering, a conductor is an object or type of material that allows the flow of charge (electrical current) in one or more directions. Materials made of metal are common electrical conductors.
semiconductor
Semiconductors are materials which have a conductivity between conductors (generally metals) and nonconductors or insulators (such as most ceramics). Semiconductors can be pure elements, such as silicon or germanium, or compounds such as gallium arsenide or cadmium selenide.
insulator
An electrical insulator is a material in which the electron does not flow freely or the atom of the insulator have tightly bound electrons whose internal electric charges do not flow freely; very little electric current will flow through it under the influence of an electric field.
1. Insulator?
An insulator is a material that has very high electrical resistance & it does not allow the flow of current. There are no free electrons in insulators thus they do not conduct electricity. Thus they are used for protection against
2.Semiconductor
Semiconductors are materials that have conductivity in-between conductors and insulators. They can block or allow the current flow providing total control over it. They are mostly modified by adding impurities called doping.
3. Conductor?
In Electrical & Electronics engineering, a conductor is a type of material that allows the flow of charge otherwise known as electrical current. Most common electrical conductors are made from metals.
