Who is good conductor of electricity?

Copper is still the most popular material used for wires because it is a very good conductor of electrical current and it is fairly inexpensive when compared to gold and silver. Aluminum and most other metals do not conduct electricity quite as good as copper.

Who is the best conductor of electricity?

The best conductor of electricity is pure silver, but to no surprise, it is not one of the most commonly used metals to conduct electricity. The wide use of pure silver has a couple of drawbacks.

Is good a good conductor of electricity?

Graphite is a good conductor of electricity because it has free electrons.

Which is a conductor of electricity?

An electrical conductor is a substance in which electrical charge carriers, usually electrons, move easily from atom to atom with the application of voltage. … Copper, steel, gold, aluminum, and brass are also good conductors.

Is Diamond a good conductor of electricity?

As we know diamond is a giant covalent structure i.e. each carbon atom is covalently bonded with other carbon atoms. So the four outermost electrons, four carbon atoms, are engaged or trapped in the covalent bonds which means that there are no free electrons. … So diamond is a bad conductor of electricity.

Is Mercury a good conductor of electricity?

Mercury is the only metal that is liquid at standard conditions for temperature and pressure. Mercury is a poor conductor of heat, but a fair conductor of electricity. … Mercury dissolves to form amalgams with gold, zinc, and many other metals.

Who is the bad conductor of electricity?

Difference between Good Conductor and Bad Conductor of Electricity

Good Conductors Bad Conductors
Example – Copper, Aluminium Example – Rubber, Wood
Can be used to make electric circuits. Can not be used to make electric circuits.

Why is good conductor of electricity?

Metals are an excellent conductor of electricity and heat because the atoms in the metals form a matrix through which outer electrons can move freely. Instead of orbiting their respective atoms, they form a sea of electrons that surround the positive nuclei of the interacting metal ions.

Why is i2 not a good conductor?

Conductor of Eletricity: Iodine does not conduct electricity since each molecule of iodine comprises two iodine atoms joined by a covalent bond that cannot be excited sufficiently to transfer electrical energy.

What is a good conductor and why?

Copper and Silver Are Most Common

For a material to be a good conductor, the electricity passed through it must be able to move the electrons; the more free electrons in a metal, the greater its conductivity. … Most wires are copper-plated and electromagnet cores are normally wrapped with copper wire.

What are 5 good conductors?

The most effective electrical conductors are:

  • Silver.
  • Gold.
  • Copper.
  • Aluminum.
  • Mercury.
  • Steel.
  • Iron.
  • Seawater.

Why are silvers good conductors of electricity?

A conductor is a material which gives very little resistance to the flow of an electric current or thermal energy. … Silver is the best conductor because its electrons are freer to move than those of the other elements, thereby making it more suitable for the conduction of electricity and heat than any other element.
