You asked: Why is copper wire used instead of wood in an electric circuit?

Answer: Copper electrical wires are safer to use than wires made of most other conductive metals because they are resistant to heat. … It has high electrical conductive; it’s inexpensive; it’s ductile; and it’s thermal resistant.

Why only copper wire is used in electricity?

Why is copper used for most electrical wiring? … The lower the level of resistivity, the more electrical conductivity a metal has. Copper has low resistivity, and therefore is an excellent conductor. Copper is also less oxidative than other metals.

Why is copper useful?

Most copper is used in electrical equipment such as wiring and motors. This is because it conducts both heat and electricity very well, and can be drawn into wires. It also has uses in construction (for example roofing and plumbing), and industrial machinery (such as heat exchangers).

GOOD TO KNOW:  Frequent question: Do ionic compounds conduct electricity when dissolved in water?

Refrigerators, stoves, and air conditioners in particular are great sources of copper as they require a larger power supply and therefore tend to contain thick insulated copper wire.
