Electricity,electrons and type of conductor
What Is Electricity
The flow of electrons in the conducting material is called current. Its flow cannot be seen, only its effect can be felt! According to this, the current in a clever wire flows only when the electrons move from one end of it to the other.
What is Electrons
The smallest particle of any substance found in nature is called Molecule. And the smallest particle of a molecule is called an atom. The nucleus of an atom consists of protons and neutrons.
These two numbers are equal. Protons are in positive charge, the particle that bounces around protons and neutrons is called electrons. It has negative charge.
What is Free Electrons
Some of the electrons revolving around the nucleus of the atom can be easily separated. The separated electrons are called free electrons.
It is because of these free electrons that current flows in the wire.
Types of materials
Conductive material:
The substance that allows an electric current to pass easily inside it is called conductive material. Such as: Gold, Silver, Iron, Copper, Aluminum, nickel Etc.
Non-conductive material:
The substance which does not allow any electrical current to pass through it is called as non-conductive material. Such as: Wood, Plastics, Mica, Rubber Etc.
Semiconductor Material:
Substances that allow the current to pass through the inside to a certain extent are called semiconductor materials. Such as: Germanium, Silicon Etc.
