Correct Answer - Option 3 : Annealed copper

Annealed Copper:

  • Due of superior conductivity, annealed copper became the international standard to which all other electrical conductors are compared.
  • In 1913, the International Electrotechnical Commission defined the conductivity of commercially pure copper in its International Annealed Copper Standard.
  • Copper is used as the electrical conductor in many categories of electrical wiring.
  • Copper wire is used in power generation, power transmission, power distribution, telecommunications, electronics circuitry, and countless types of electrical equipment.
  • Copper and its alloys are also used to make electrical contacts. Electrical wiring in buildings is the most important market for the copper industry.
  • Roughly half of all copper mined is used to manufacture electrical wire and cable conductors.

Aluminium:-

  • An aluminium wire have a 1.5 times larger cross-section to pass the same current as a copper wire, but two times lighter.
  • Weight is one of the most important parameters for high-voltage power lines that transmit power over long distances.
  • Therefore, only aluminium wires are used in main overhead power lines.

Hard drawn copper:-

  • Hard drawn copper has high electrical conductivity and great tensile strength.
  • Use in transmission lines.

Silver:-

  • Because of best thermal and electrical conductivity among all metals, it is best for electrical applications.
  • Its cost is high and less abundance on Earth so have limited applications.
