The energy band formed by a series of energy levels having valence electrons is called as valence band. At 0 K, the electrons fulfill the energy levels in valence band initialising from lowest one.
(i) This band is always fulfilling by electron.
(ii) This is the type of maximum energy.
(iii) Electrons are not capable of enhancing energy from external electric field.
(iv) No flow of current because of such electrons.
(v) The highest power level which may be placed by an electron in valence band at 0 K is known Fermi level.
Give the graphical representation of the end on view of plane polarized light and unpolarized light.
A 30-g car rolls from a hill 12 cm high and is traveling at 154 cm/s as it travels along a 275 cm horizontal track. What is the momentum of the car?
Working: When plate potential (V p ) is positive, plate current ( I p ) flows in the circuit (because some emitted electrons reach to plate). If + V p enhances I p also increas
Working Principle of D.C Motor A) An electric motor is a machine which changes electrical energy into mechanical energy. B) When a current carrying conductor is placed in a
Standing OR Stationery Waves: When two identical waves of similar amplitude and period moving along the similar line in opposite directions superpose each other, a latest set o
Q. Why can a DC ammeter not read AC? a) Dc ammeter can't measure ac because ac is changing continuously and periodically as well as a dc ammeter can just measure a constant cur
An unknown material has a normal melting/freezing point of -26.3° C, and the liquid phase has a specific heat capacity of 160 J/(kg · C°). One-tenth of a kilogram of the solid at -
Johannes Kepler revealed three empirical laws by using the data on planetary motion, pertaining to the orbit of planets. These laws are contained here because of the huge importanc
A right triangular prism has volume equal to 288 cm^3. The height of the prism is 3 cm. One of the bases of the triangular face (not the hypotenuse) is equal to 12 cm, determine th
