Which metal is used as the base material in Metal Oxide Varistor?

Which metal is used as the base material in Metal Oxide Varistor? Correct Answer Zinc

The correct answer is option 4 i.e Zinc.

  • Metal Oxide Varistor (MOV) is used for the protection of heavy electrical devices from lightning or over-voltage surges.
  • MOV contains a ceramic mass of zinc oxide grains sandwiched between two metal plates (the electrodes).
