What actually mica is?

Sireesha said:   7 years ago
Any material occurring mineral that based on a collection of silicate minerals and composed of varying amounts of potassium iron, aluminium, magnesium and water is mica in capacitor it acts as an insulator.

Saikiran said:   7 years ago
Mica has highest dielectric strength among all materials. Dielectric strength is directly prorpotional to permittivity.

So, highest dielectric strength means it can strore high amount of energy.
