Which material is commonly used as an electrical conductor in daily use?
Correct answer: A. Copper
- A. Copper
- B. Aluminium
- C. Steel
- D. Nickle
Explanation
Copper is the most common material used as an electrical conductor in daily use. Copper has high electrical conductivity, making it an excellent choice for various electrical applications such as wiring, cables, and electrical components.The other options are less suitable as common electrical conductors

About Current Electricity
Steady current relates charge flow to potential difference, resistance and resistivity, including how temperature changes a conductor's resistance. Sources with internal resistance have terminal voltage below their emf when delivering current, and maximum power output occurs under a specific load condition rather than at zero resistance.
