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.
A galvanometer with a coil of resistance 120 ohm shows full scale deflection for a current of 2.5 mA. How will you change the galvanometer into an ammeter of range 0 to 7.5 A? Veri

What is an optical port? In the fiber optics industry, optical port is the component that physically produces the connection or interface in between the harness and the illumin
sir, I am in class xii and i have to submit a project:working model on any topic in physics. so please help me figure this out
The effects of open circuits: An open circuit is essentially a break in the circuit. An open circuit in a series circuit will prevent the flow of current through the circuit. W
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
