Which of the following is NOT an electrical insulator?

Which of the following is NOT an electrical insulator? Correct Answer Gold

The correct answer is Gold.

Key Points

  • Gold is not an electric Insulator.
  • Gold is a good conductor of electricity.
  • An electrical conductor is a substance in which electrical charge carriers, usually electrons, move easily from atom to atom with the application of voltage.
  • Good conductors of electricity: Gold, silver, copper, aluminum, and graphite.
  • Pure elemental silver is the best electrical conductor.
