Explain the suitability of aluminium as an electrical conductor with respect to its mechanical and electrical properties.
Explain the suitability of aluminium as an electrical conductor with respect to its mechanical and electrical properties.
Last answer:
Following are requirements of conductor:- i) High conductivity : Material should have high conductivity, So that * cross section of conductor (size) reduces, * Copper losses reduces, * So Efficiency ... . Boiling point is 1820°C 9. Specific gravity is 2.7 10. High resistance to corrosion.
