Which metal is an excellent electrical conductor and widely used for plumbing and fittings?

• A. Aluminium
• B. Copper
• C. Brass
• D. Stainless steel

Answer: (B)

Copper is ideal here because it combines two strong properties: it is an excellent electrical conductor, and it is highly suitable for plumbing and fittings. Its electrical conductivity is among the highest of common metals, which is why electrical wiring often uses copper. At the same time, copper pipes and fittings are easy to form and join, resist corrosion in water, and are safe for drinking-water systems, making them the standard choice for plumbing. Aluminium conducts well but is less durable in moist environments and harder to join reliably for plumbing. Brass is softer and contains zinc, which lowers its electrical conductivity and can lead to issues in water systems. Stainless steel conducts electricity poorly compared with copper and is more costly and harder to work with for typical plumbing fittings.
