What is the difference among Free Electron Theory and Band Theory of solids?
Free Electron Theory:
This theory says that, metals conduct electricity due to the presence of free electrons in it. The outermost shells of metal atoms will be loosely bound with their nucleus. So the electrons in it are free to move anywhere in the solid.
These electrons are known as free electrons and these electrons are responsible for the conduction of electricity.
what is deforming force
The force acting between two point charges can be computed using which of the following laws? a) Ohm's Law b) Ampere's Law c) Coulomb's Law d) Newton's Second L
As an electron passes close to the positive nucleus of atom, the electron is moved from its path as given in diagram. This results in deceleration of the electron. The loss in powe
