What makes a conductor a good conductor?

Solution

Conductor:

  1. Materials with a lot of electron mobility are called conductors.
  2. A good conductor of electricity is one that permits electrons to freely flow through it.
  3. Electrons are electrically charged particles that can be found in a variety of substances.
  4. An electric voltage is applied to the electrons at specific locations, causing them to migrate and allowing electricity to pass through.
  5. The ability of a material to conduct electricity is referred to as conductivity.

Properties of a good conductor:

  1. It has very low resistance.
  2. In general, a good conductor of electricity is also a good conductor of heat.
  3. In general, a good conductor is malleable and ductile.

Therefore, electricity must be able to flow through metal to make it a good conductor. The more free electrons in a metal, the better its conductivity.
