Which material is a good conductor of electricity Milady?

What is an example of a good conductor Milady?

Any material that easily conducts electricity. Examples of good conductors? Metal, copper, and water.

Which is considered a good conductor?

Copper is considered to be a conductor because it “conducts” the electron current or flow of electrons fairly easily. Most metals are considered to be good conductors of electrical current. … Other materials that are sometimes used as conductors are silver, gold, and aluminum.

What are two types of electric current Milady?

Direct Current: *Constant, even-flowing, Travels in one direction, and produced by chemical means. Alternating Current: *Rapid and interrupted flow, Travels in two directions, and produced by mechanical means.

What is another name for materials that are non conductors?

Non-conductive materials, also known as insulators, are materials that either prevent or block the flow of electrons.

What is a good example of a good insulator?

Is Diamond a good conductor of electricity?

In a graphite molecule, one valence electron of each carbon atom remains free, Thus making graphite a good conductor of electricity. Whereas in diamond, they have no free mobile electron. Hence there won’t be flow of electrons That is the reason behind diamond are bad conductor electricity.
