Why are copper metal wires used to conduct electricity?

For example, because copper is a good electrical conductor, it is used for electrical wiring. Since the metal particles are bonded to one another by a strong metal bond, they have a high melting point and boiling point. Allowing free electrons in the metal to pass through the metal and conduct the metal

Silver is the best conductor because silver contains more mobile atoms (free electrons). In order for the material to be a good conductor, the current through it must be able to move electrons; the more free electrons in the metal, the greater its conductivity.

The problem with Sterling Silver Silver is that it may lose gloss. This problem can cause problems in applications where skin effect is important, such as high frequency current. It is also more expensive than copper and a slight increase in conductivity is not worth the cost.

The concentration of free electrons in the gold metal was 5.91 × 10 22 cm -3. Gold has strong conductivity and has been used for electrical wiring in several high energy applications (only silver and copper are more conductive in each volume, but gold has advantages of corrosion resistance). For example, gold wire was used in some atomic experiments in Manhattan, but a large current silver wire for the Cartlone isotope separation magnet was used in this project.

Metal is conductive, but rubber is not. Gold conductivity; polystyrene foam does not. Most materials can be easily divided into either. For example, if good wires are needed, everyone knows that they need to be made of copper rather than plastic. But in the meantime there is a series of materials. Their conductivity is between the metal and the insulator. And their conductivity can be corrected instantaneously by irradiating light or injecting charge thereon. They were called semiconductors and became the first physicist's interest in the late 1920s.

Early in the 1920s, British scientist Michael Faraday discovered the meaning of power generation. He moved a conductive metal ring or disk between the magnets poles. The basic principle is that electrons in a copper wire can move freely. Each electron has a negative charge. The movement is controlled by the attractive forces between electrons and positive charges (such as protons and positively charged ions) and repulsive forces with electrons and similar charges (such as other electrons or negatively charged ions). In other words, the electric field around the charged particles (in this case, electrons) exerts a force on the other charged particles and makes them move and function. Forces must be exerted to keep the two attracted charged particles away from one another
