Among mica, gold, copper and silver, which one is the best conductors of electricity?

Among mica, gold, copper, and silver, copper and silver are the best conductors of electricity. Both copper and silver have high electrical conductivity compared to other common materials.

While silver has the highest electrical conductivity among all metals, copper follows closely behind. However, copper is more commonly used in electrical applications due to its lower cost compared to silver.

Gold also has good conductivity, but it is less commonly used in electrical applications due to its high cost.

Mica, on the other hand, is an insulating material and does not conduct electricity. Therefore, it is not suitable for use as a conductor.
