Question

why is copper used for most electrical wiring?
it has high voltage.
it has low voltage.
it is a good conductor.
it is a good insulator.

Explanation:

Copper is widely used in electrical wiring because it has low electrical resistance, making it a good conductor of electricity. Voltage is not a property inherent to the material itself but rather related to the electrical source in a circuit. Insulators do not conduct electricity well, and copper is not an insulator.

Answer:

C. It is a good conductor.
