Which mineral has a hardness of 2.5 3 and makes a good electrical insulator?
Biotite mica
What does Good electrical insulator mean?
An insulator is a material that does not conduct well, so an electrical insulator is a material that does not conduct electricity well. A metal is a bad electrical insulator as it has delocalised electrons, therefore conducts electricity, but most plastics and materials like rubber do not conduct electricity, so they are good electrical insulators. Hope that makes sense and helps? :3AnswerAn insulator is a material with insufficient free charge carriers to support conduction.
What mineral is used to make salt?
there are three things to know what makes a up a rock 1 color 2 shape 3 hardness 4 streak 5 luster i hope that answers your question
What type of mineral makes up limestone?
The mineral quartz makes up limestone.
What does insulate mean in electrical wiring?
An insulator is some material which creates a barrier for some form of energy, and makes it difficult for that energy to pass; the usual types would be electrical insulators (such as the plastic that is wrapped around wires), heat insulators (such as clothing, fiberglass insulation etc.), or acoustic insulators which impede the passage of sound (acoustic tiles, or thick walls are examples).
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
What mineral makes hardness?
calcium
What unusual charateristic does mica have and how is it useful?
Mica is a soft mineral (Mohs hardness of 2-2.5), and has perfect cleavage in one direction. It also has a shiny luster, which makes it useful in paint and makeup manufacture. It is used as an insulator in electrical equipment and because of its resistance to heat it has been used as a replacement for glass in furnace and stove windows. The low hardness makes it useful as a very mild abrasive, and it is used in some toothpastes.
What makes a good electrical insulator?
An electrical insulator is a material whose internal electric charges do not flow freely. Rubber, glass, paper, and Teflon, which have high resistivity, are very good electrical insulators.
What is difference between hardness and streak?
Streak is the color it makes when two minerals scratch against each other. Hardness is just how hard the mineral is

Why is tape a good insulator?
Duct Tape is made of rubber and since rubber is a good insulator that makes duct tape a good insulator. The best tape for insulating is electrical tape.

What is the mineral with a hardness of 1 on the Mohs scale?
Talc is the mineral with a hardness of 1 on the Mohs scale.
Why glass is a good insulator?
Glass makes a good insulator for electrical systems because glass will not melt too easily. Glass is also a good insulator on a house because air cannot pass directly through the glass.
What makes something a good insulator?
Trapped air makes a good insulator.
