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.
Write down Gauss law in electrostatics. get its differential form in vacuum.
(1) Holes works as virtual charge, although there is no charge on holes. (2) Effectual volume of hole is more than electron. (3) Mobility of hole is fewer than electron.
why the reflective index of cladding is lower then in core of a fiber optic?
Voltage division: In a series circuit Ohm's law applies for each component. However, since the current is common to all components we have: V1 = IR1, V2 = IR2,
