Explanation:
hey here is the answer
The mica group represents 37 phyllosilicate minerals that have a layered or platy texture. The commercially important micas are muscovite and phlogopite, which are used in a variety of applications. Mica's value is based on several of its unique physical properties. The crystalline structure of mica forms layers that can be split or delaminated into thin sheets usually causing foliation in rocks. These sheets are chemically inert, dielectric, elastic, flexible, hydrophilic, insulating, lightweight, platy, reflective, refractive, resilient, and range in opacity from transparent to opaque. Mica is stable when exposed to electricity, light, moisture, and extreme temperatures. It has superior electrical properties as an insulator and as a dielectric, and can support an electrostatic field while dissipating minimal energy in the form of heat; it can be split very thin (0.025 to 0.125 millimeters or thinner) while maintaining its electrical properties, has a high dielectric breakdown, is thermally stable to 500 °C (932 °F), and is resistant to corona discharge.

Answer:
IT IS MAINLY FOUND IN IGNEOUS AND METAMORPHIC ROCKS AND PENINSULAR ROCK SYSTEM.
DUE TO ITS GOOD DI ELECTRIC STRENGTH , HIGH RESISTANCE TO POWER , LOW POWER LOSS FACTOR IT IS MAINLY USED IN ELECTRIC INDUSTRIES.
ANDHRA PRADESH IS LARGEST MICA PRODUCING STATES.
