Mica has such poor electrical conductivity that it has often been used as an insulator. The resistivity of mica ranges from 1x10^12 to 2x10^14 Ω/cm depending on the type of mica. For reference, copper, a good conductor, has a resistivity of only 1.68×10^−8 Ω/m or 1.68x10^-10 Ω/cm.
no, it is an insulator.

∙ 13y agoMica is commonly used in insulation of electricity between high heat generating transistors and their heat sink and or chassis to prevent grounding out of component and to assist in the transfer of the generated heat to the heat sink or chassis for dissipation, also MICA is quite often used in industrial heating equipment to electrically insulate the heating element from the object to be heated thus yes MICA does quite well conduct heat under the proper conditions.

Which is the best electrical insulator?
According to a few charts I was able to find, the most realistic material with the highest dielectric strength happens to be Mica, with dielectric strength of 118.
Define mica capacitor?
A mica capacitor is simply one that uses the mineral mica as the dielectric or insulator between plates.
What is the best known insulator of electricity?
The most common electrical insulator is the plastic coating on electrical wires. Hope this helps!
What mineral is oftern used as an insulator in electrical equipment?
what is plaster of paris made of
Silicon electrical conductivity?
Varies dramatically with dopant concentration. Pure silicon is almost an insulator.
What mineral is often used as an insulator is electrical equipment?
Mica. Mica Mica
One substance sometimes used as an electrical insulator is?
mica
Is mica a ceramic insulator?
Mica is both an electrical conductor as well as a good thermal conductor. Block mica is used primarily in electronic equipment.
Is mica a good electrical insulator?
First AnswerYes it is and it can also withstand heat. For many years mica was used in toasters to make a framework to hold the heating elements.Next AnswerActually mica is a very good electrical INSULATOR, but is a good THERMAL conductor, which is why it was used for holding heating elements.
Which mineral has a hardness of 2.5 3 and makes a good electrical insulator?
Biotite mica
Which mineral has a hardness of 2.5-3 and makes a good electrical insulator?
Biotite mica
Is mica a conductor or a insulator?
Mica is an insulator of electricity and heat.
What is mica's colors?
Mica comes in a variety of forms and colors. The most common micas are biotite, which is dark colored, and muscovite, which is light in color.
An electrical insulator has what?
In case of electrical insulator the electrons are tightly bound to the nuclei of the atoms and no free electrons are available. In reality free electrons are the carriers of electrical charges through the conductor. As free electrons are not available then current becomes zero for even little bit high voltages. Glass, mica, rubber are examples.
