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.
What would make a good insulator?
A nonmetal would make a good insulator.
What make plastic an important safety material?
It is an insulator!!
What would make 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.
Is a material a good insulator if outer electrons of atoms in the material are free to roam around?
No, a material with outer electrons that are free to move easily is a good conductor of electricity, not a good insulator. Insulators are materials that have tightly bound outer electrons, which do not move easily, leading to limited flow of electricity.
What material is used to make the heating coils of electrical heating device and why?
Nichrome
How can you make a material change its state?
Often you can make a material change state by heating or cooling it
How do you make a good insulator?
To make a good insulator, use materials with high resistance to heat or electricity, such as rubber, glass, or plastic. Ensure the insulator has low thermal conductivity to minimize heat transfer and is thick enough to provide effective insulation. Properly insulating the object or area by covering it completely with the insulating material will help prevent the flow of heat or electricity.
Is fiberglass an insulator or a conductor?
Fiberglass is an insulator. Its properties make it a good electrical insulator because it does not conduct electricity well.
Which of these would make a good electrical insulator?
rubber
How does material of high porosity make good thermal insulator?
Material with high porosity contains many small air pockets within its structure, which hinders the transfer of heat through conduction. These air pockets trap air molecules, preventing heat from easily passing through the material. This makes the material an effective thermal insulator by reducing heat transfer through conduction.
What TA make a good insulator?
Trapped air makes a good insulator.
