Differencitate between
Conductor and instalator
Answers
Answer:
material which allows electricity to pass through them are called conductor.
and the material which do not allows electricity to pass through them.
Answer:
Insulator
The materials which do not allow the electric current or heat to pass through it such type of material is called an insulator. The covalent bond between the atoms of an insulator is very strong.Thus, the electrons or charges do not move freely. The resistivity of the insulator is very high.
The forbidden gap between the valence band and conduction band of an insulator is very large, and hence the electrons require large energy for moving from valence band to conduction band.
Conductors
The conductor is defined as the material which allows the electric current or heat to pass through it. The electrons in a conductor freely moved from atom to atom when the potential difference is applied across them. The conductivity of the conductor depends on the number of free electrons in the outermost shell of the orbit. The conductivity of the material is directly proportional to the number of free electrons.
The conductivity of the material is directly proportional to the number of free electrons.The valence band and conductance band of a conductor are overlapped each other and hence there is no forbidden energy gap. The resistance of the conductor is very low due to which the charges freely move from place to place when the voltage is applied across them. Copper, aluminium, silver, mercury, etc. are some of the examples of the conductor.
