Question

how conductor differ insulator on the basis of their specific heat capacity

Answer 1

the specific heat capacity of a conductor is very low but the specific great capacity of an insulator is very high

Answer 2

Definition
Material which permits the electric current or heat to pass through it.
Restrict the electric current or heat to pass through it.
Electric Field
Exist on the surface but remain zero inside the conductor.
Do not exist on insulator.
Magnetic Field
Store energy
Do not store energy
Potential
Remain same at all the point on conductor.
Remain zero.
Thermal Conductivity
High
Low
Covalent bond
Weak
Strong
Conductivity
Very high
Low
Resistance
Low
High
Electrons
Freely move
Do not move freely
Resistivity
Vary from high to low
High
Temperature coefficient
Positive temperature coefficient of resistance
Negative temperature coefficient of resistance
Conduction band
Full of electrons
Remain empty
Valence Band
Remains Empty
Full of electrons
Forbidden gap
No forbidden gap
Large forbidden gap
Examples
Irons, aluminum, silver, copper, etc.
Rubber, wood, Paper, etc.
Application
For making electrical wires and conductor
As a insulation in electrical cables or conductor, for supporting electrical equipment etc.
