Why do conductors conduct electric current very easily?

Conductors conduct electrical current very easily because of their free electrons. Insulators oppose electrical current and make poor conductors. Some common conductors are copper, aluminum, gold, and silver.

Why do conductors conduct electric current easily?

They conduct electricity because they allow electrons to flow easily inside them from atom to atom. … Conductors have free electrons on its surface which allow current to pass through easily. This is the reason why conductors are able to conduct electricity.

What things conduct electricity easily?

Metals are generally very good conductors, meaning they let current flow easily. Materials that do not let current flow easily are called insulators. Most nonmetal materials such as plastic, wood and rubber are insulators.

Why do metals conduct electric charge easily?

-Metals conduct electricity because the electrons inside the metal are quite free to move. … -The valence electrons travel through the lattice of the metal and carry the electric charge with them. -Metals have very less band gap between valence band and conduction band, sometimes they are overlapped also.

What are 5 good conductors?


  • silver.
  • copper.
  • gold.
  • aluminum.
  • iron.
  • steel.
  • brass.
  • bronze.

What is an example of a good insulator?

Wool, dry air, plastics, and polystyrene foam are all examples of good insulators. Materials that do not insulate well are called conductors. Conductors have loose bonds that allow particles to move easily and transfer energy from one particle to the next.

What are good conductors for electricity?

Most metals are considered to be good conductors of electrical current. Copper is just one of the more popular materials that is used for conductors. Other materials that are sometimes used as conductors are silver, gold, and aluminum.

Why metal is a good conductor of electricity?

Metal form crystal lattice. … Thus, on applying heat the electrons of metal become mobile and conduct electricity. So, the metals conduct electricity due to the presence of free electrons. So, metals are good conductors of electricity because metals have free electrons.

What makes electric charges flow?

Answer Expert Verified. Electric current or electric charges flow because of the Coulomb’s force on them . The force is due to electric field. The field is created because of potential difference between two end points of a conductor.

Why do metals conduct electricity so well?

Metals conduct electricity because they have “free electrons.” Unlike most other forms of matter, metallic bonding is unique because the electrons are not bound to a particular atom. This allows the delocalized electrons to flow in response to a potential difference.
