Why is copper used in household wiring?
Correct answer: C. Good conductivity and ductility
- A. High resistivity
- B. Magnetic properties
- C. Good conductivity and ductility
- D. Reacts with water
Explanation
Copper is used in household wiring primarily because of its excellent electrical conductivity and ductility. These properties allow it to efficiently carry electric current and be easily shaped into wires. In contrast, materials with high resistivity hinder electrical flow, magnetic properties are irrelevant for non-magnetic copper in wiring, and reactivity with water would make a material unsuitable for durable electrical applications.

About Scientific Reasoning
Scientific reasoning evaluates hypotheses through observations, variables, controls, measurements and experimental results. Questions involve identifying independent and dependent variables, recognising a fair test, interpreting tables or graphs, distinguishing evidence from opinion, and deciding whether data supports, rejects or leaves a hypothesis unresolved.
