Which metal is commonly used for electrical wiring due to its excellent conductivity and ductility?
easy Q1 of 15
Step-by-Step Solution
Step 1: Understand the concept
The question tests knowledge of metals used in electrical wiring based on conductivity and ductility.Step 2: Apply the concept
Copper is widely used in electrical wiring because it has excellent electrical conductivity and is ductile, allowing it to be drawn into thin wires. Aluminium is also used but less conductive than copper. Iron and lead have poor conductivity.Final Answer:
Copper → Option CQuick Check:
Metal for electrical wiring = Copper ✅
Quick Trick: Copper has highest conductivity among common metals.
Common Mistakes:
- Confusing aluminium with copper due to aluminium's light weight.
