Each substance is composed of atoms. Inside the atom, the fundamental particles are protons, the negative particle electrons and the charged particles are neutrons, the number of protons and electrons in any object is equal. If some electrons are removed from an object then the number of protons in the object will be greater than the number of electrons, so that the object will be chested. If some electron is given out in the object, then the number of electrons in the object will exceed the number of protons. This will cause the debt to become debt-free. This made it clear that the original source of electric charge is proton and electron. They exist only in the object. When the electrons fall in or decrease in the object, the object is either coronal or indebted.
The electrodynamics can be possible between the substances through which electric charge can move from one place to another, such as metals, acids, alkalis, aquatic solution of salts etc. These are all examples of electrical conductive substances, through which the electrical charge can not go from one place to another, they are called electrically-like wood, rubber, asbestos, paper, pure distilled water etc. But on adding a little acid or alkali or salts it works like a conductor. Increasing the heat increases the electrical resistance of the conductor and its electrical conductivity decreases.
We know that in the process of the substance of the substance, only the electrons go out of the substance or come into the matter from the outside. The transfer of some electrons of the substance within the substance is called electrodynamics. Those electrons that can be transferred within the substance are called free electrons of matter.
Michael Faraday (1791-1867)
Michael Faraday was an experimental physicist. He did not get any formal education. In the early period of his life, he worked at the shop in the shop. Faraday used to study books coming to the shop for the bookkeeping. This generated interest in his science. They got the opportunity to hear public lectures from the Royal Institute scientist Sir Humphrey Davy. He carefully prepared the notes of the lectures of Dewey and sent him to Sir Davey. Soon he was made assistant at DAVY Laboratory at the Royal Institute. Faraday did many revolutionary searches, including the rules of electrical magnetic induction and electrical decomposition. Many universities attempted to award honorary titles to them, but they rejected such honors. Faraday had more love than his scientific works than any honor.
In addition to the driver and non-electromagnetic substances, there are some substances that are present between their electrical conductivity, driver and dielectric substances.
Such substances are called semi-drivers, if the heat of the semi-conductor is increased too high or some inaccuracies are mixed, then they act like a substance driver. Conductivity of semi-conductor material increases on heating and decreases on heat removal. Semi-conductor treats on the ultimate zero heat, like the ideal conductors. The prime examples of semi-conductor are carbon, germanium, silicon etc.
