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.

INDUCTOR:- An inductor (also choke, coil, or reactor) is a passive two-terminal electrical component that stores energy in its magnetic field. For comparison, a capacitor stores en
Input Capacitor C in An ac signal is supplied to gate of the FET through an electrolytic capacitor known as input capacitor C in . This capacitor allows only ac
Q. Collector current I c =20 mA and base current I b = 50 A. Find current gain β of a transistor. β = I C / I B = 20 X 10 -3 / 50 X 10 -6 = 400
Q. Find the minimum wavelength of X-rays produced by an X-ray tube operating at 1000 kV. λmin = 12400 A 0 / V Therefore λmin = 12400 X 10 -10 / 10 6 = 0.0124 A 0
