What is the difference between Conductor and Insulator?

The main difference between the conductor and insulator is that Inductor allows the energy (current and heat) to pass through it. In the conductors, electron freely moves in the outer shell and the conductivity of the conductor depends on the number of electrons freely move in the outer shell.

Whereas the insulator does not allow the energy (heat and energy) to pass through it. Between the atoms of insulators, a covalent bond stronger due to which atoms cannot move freely and the resistivity is high in the insulators. To separating the conductors, insulators are used mainly.

What is the difference between Conductor and Insulator?

Key difference

  • Conductor permits heat and current to pass through it whereas insulator does not permit heat and current to pass through it.
  • On the surface of the conductor, the electric field exists but remains zero inside the conductor whereas, in the case of insulators, the electric field does not exist in the insulators.
  • In conductors, the magnetic field store energy whereas in insulators magnetic field does not store energy.
  • Potential remains the same on all points in the conductor whereas in the insulator potential remains zero.
  • Thermal conductivity has by conductors whereas it not have by insulators.
  • The covalent bond is weak in the conductors whereas strong in the insulators.
  • Conductors have low resistance whereas insulators have high resistance.
  • Electron freely moves in the conductors but cannot freely move in the insulators.
  • Iron, copper, and silver are examples of conductor and Rubber, wood, and paper are examples of insulators.
