Copper has been used in electrical wiring since the invention of the electromagnet and the telegraph in the 1820s. The invention of the telephone in 1876 created further demand for copper wire as an electrical conductor.. Copper is the electrical conductor in many categories of electrical wiring. Since heat increases when the subatomic particles are able to move without resistance throughout the metal, copper is a good conductor of heat. BUT… tin is one of the main ingredients in electrical solder. Tin is an electrical conductor. Those materials which allow electricity to pass through them are called good conductors of electricity Example Solids like Copper, Aluminium conduct electricity Liquids like Tap Water, Lemon Juice, Mercury conduct electricity Bad Conductor of Electricity Those materials which do not allow electricity to pass through them are called Bad Conductors Example Solids like Rubber, Plastic, Wood … Copper is also a good thermal conductor. That is one reason that it is used for electrical wiring. If heat is applied to one end of a cooper wire, it travels quickly to the other end, as the electrons move unimpeded by resistance. Therefore the energy losses in the aluminium cable will be higher than in the copper cable. An aluminium cable would have nearly twice the resistance of a copper cable with the same dimensions. Hence copper is not an electrolyte, despite of being a good conductor of electricity. Because Copper is an excellent electrical conductor, most of its common uses are for electrical purposes. As I said, copper is a better conductor than most, however, silver is a better conductor. As each electron is detached, electricity is allowed to function. But its volumetric resistivity is significantly higher than that of copper, so you won’t see it used for wires, circuit board traces, bus bars, etc. This means that the resistance of a length of copper cable is relatively low. Many common applications also rely on one or more beneficial properties, such as the fact that it is a good thermal conductor or has low reactivity (reaction with water and acids). Copper is a metal that is a good conductor of electricity. Since copper’s electrons detach easier than most other conductors, electricity easily functions through a copper circuit. The copper cable is more energy efficient. Copper metal, being a solid, has no mobile ions whereas an electrolyte should dissociated into oppositely charged ions to be able to conduct current. This is what really makes copper such a good conductor. Copper is a very good electrical conductor. However, due to the large cross section of copper in the pipe wall, this increased resistance is nullified. Copper pipe is not as pure copper as that used in wire, an amount of lead is added to make the pipe easy to bend.
