The best conductor of electricity is:

The best conductor of electricity is:

  • (A) Iron
  • (B) Aluminium
  • (C) Copper
  • (D) Silver
Among the elements, silver is the best conductor of electricity. The way the atoms are arranged in silver allows the valence electrons to flow freely, and this is why silver has the highest electrical conductivity and lowest resistivity. On a standard scale, silver is rated at 100, while copper is rated at 97, and aluminum is rated at 61. Even though silver is the best conductor, it is not used in household wiring due to its high cost and tendency to tarnish.
