Which property makes copper useful in electric wires?

Answer and explanation

Correct answer: Electrical conductivity

Copper is a very good conductor of electricity, so electric current can pass through it easily; therefore, it is used in electric wires. Thermal conductivity concerns the flow of heat, not electric current. Copper’s ductility also helps in drawing it into wires, but the main property for its electrical use is electrical conductivity. Exam tip: distinguish conductivity for carrying current from ductility for making wires.
