FAQ

Those who are looking for an answer to the question «Is copper or aluminium a good conductor of electricity?» often ask the following questions:

♻️ Why copper is a good conductor of electricity than aluminium?

To attribute to an aluminium conductor the same resistance as a copper conductor, the cross-sectional area of the aluminium conductor must become larger to compensate for aluminium’s higher electrical resistivity. In fact, for the same current-carrying capability, an aluminium conductor needs a 56% larger cross-sectional area than copper.

♻️ Is aluminium good conductor of electricity?

Aluminum is a good conductor because it is a metal. In metals, the valence electrons are already detached due to the metallic bonds between atoms. We call these electrons that break the bond with their atom free electrons

♻️ Which is best conductor of electricity copper or aluminium?

In order of decreasing conductivity we have silver, copper, gold, aluminum, tungsten (a poor second to aluminum), stainless steel ( miserable) and mercury which is about 40 time poorer than aluminum. Now if one considers weight, aluminum is much b...

Why copper is good conductor of electricity?

Answer Copper metal, being a solid, has no mobile ions whereas an electrolyte should dissociated into oppositely charged ions to be able to conduct current. Hence copper is not an electrolyte, despite of being a good conductor of electricity.

Why is copper good conductor of electricity?

is copper the best conductor of electricity? Copper has the best electrical conductivity of any metal, except silver. A good electrical conductivity is the same as a small electrical resistance. Picture 1 A lightning conductor carries the charge safely to ground. Copper wires allow electric current to flow without much loss of energy.

Is aluminium foil a conductor of electricity?

Aluminum foil is a great conductor because conductors let electricity go through them and that means that all metals are great conductors so so is aluminum foil.

Is aluminium the best conductor of electricity?

Electric Conductivity

Most metals conduct electricity to a certain extent. Some metals are more highly conductive than others. Copper, silver, aluminum, gold, steel, and brass are common conductors of electricity. The most highly conductive metals are silver, copper, and gold.

Copper is a good conductor of electricity explain why?

Copper is a good conductor of electricity because of its huge charge density allowing more electrons to flow in its conducting system. This high charge density that copper possesses is the responsible for the slow drift of velocity that occurs when electrical charges are being discharged and transmitted.
