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.
It is the ratio of the internal electric field induced by the charges on the surface on the dielectric when an external field applied to the polarization of the dielectric.
A resistor is a two-terminal electrical or electronic component that resists an electric current by producing a voltage drop between its terminals in the accordance with ohm’s law.
It contains 35%- 90% nickels. Higher is the nickel content higher is the permeability and lower is the magnetic saturation of the alloy. MN, CO, and Mo can also be added in trace q
The Law of Reflection While a ray of light strikes a plane mirror and the light ray reflects off the mirror. Reflection includes a change within direction of the light ray. The
An ostrich can run at speeds of up to 72km/h. Suppose an ostrich runs 1.5km at the speed of 58 km/h and then runs another 1.5km at the speed of 29km/h. What is the ostrich average
Production of electricity : Very large amounts of electrical energy lie dormant in the atoms of every speck of material in the universe. Whilst the atoms remain electrically ba
In optics what is intended by the expression "constructive interference." Answer: This is factual for any kind of waves. Any time you have coherent waves of the same kind
What is a linear charge density? Answer: Note that the respond In the case of a distribution of charge in which all the charge is on a line it is the total amount of char
What are end-terminations? Again, we get ourselves in an area where many confusion and controversy are the order of the day. Several American institutions have tried to set sta
OHM’S LAW: So far you have been introduced to the concepts of electric current (as a movement of free electrons through a conducting material), voltage (or potential) and poten
