Question

What is the primary reason copper is used in household wiring?

Options

• Its resistivity decreases significantly with temperature

• It has high resistivity that prevents current flow

• It has low resistivity, allowing electric current to pass easily

• It can be doped to improve its properties

Answer 1

Copper is used in household wiring because it is a good conductor with low resistivity. This property allows electric current to pass easily through the wires with minimal resistance and heat loss, making it ideal for electrical distribution systems.
