Which metal is commonly used in making electrical wires due to its excellent conductivity and ductility?
easy Q12 of 15
Step-by-Step Solution
Step 1: Understand metals used in electrical wiring
Copper is widely used in electrical wiring because it is an excellent conductor of electricity and is ductile.Step 2: Evaluate other metals
Iron is less conductive and prone to rust; aluminium is used but less conductive than copper; lead is poor conductor and toxic.Final Answer:
Copper → Option DQuick Check:
Electrical wiring metal = Copper ✅
Quick Trick: Remember copper wires are common in homes and electronics.
Common Mistakes:
- Choosing aluminium or iron due to their availability instead of conductivity.
