Which of the following is not an insulator?

The correct answer is Mercury. Mercury is NOT an insulator. Insulators are material that does not conduct electricity. Examples - paper, plastic, rubber, glass, Ebonite, air, Styrofoam, etc.

Which is not an example of an insulator?

Pots and pans are not examples of insulators, they are conductors of heat, if it was not so, they could not be used for cooking food.

What are 4 examples of an insulator?

Examples of insulators include plastics, Styrofoam, paper, rubber, glass and dry air.

Which of the following is not an insulator Class 7?

Which of the following is not an insulator i) Bricks ii) Brass iii) Bamboo iv) Plastic. Plastic and wood are poor conductors of heat. Brass is a type of metal which is alloy of zinc and copper which readily conducts electricity. Remaining all are insulators which means it does not conduct electricity.

Which of the following is not an insulator Chapter 13?

Which of the following is not an insulator? Water is not an insulator, the ions in ordinary water make it a good conductor.

Which of the following is not an insulator ?

Is bromine a insulator?

An insulator is a material which does not allow the current to pass through it. Examples of conductors- copper, silver, graphite, etc. Examples of insulators- bromine, paper, plastic, wood, etc.

Which among the following is not an insulator Mcq?

The correct answer is Mercury. Mercury is NOT an insulator. Insulators are material that does not conduct electricity. Examples - paper, plastic, rubber, glass, Ebonite, air, Styrofoam, etc.

Is copper an insulator?

Copper is considered to be a conductor because it “conducts” the electron current or flow of electrons fairly easily. Most metals are considered to be good conductors of electrical current.

Is graphite an insulator?

Among the carbon allotropes, diamond is an insulator, whereas, graphite is a good conductor of electricity.

What are 5 insulators?

What are insulators give 5 examples?

What are some types of insulators?

Which is not example of conductor?

Sulphur, Phosphorus, Wood are non-conductors of electricity due to no presence of free electrons in outermost shell.

Is rubber an insulator?

Rubber is known to be an insulator because rubber can limit the transfer of electricity. The rubber properties prevent the electrons to be able to freely move and the addition of the electrons being tightly bounded makes rubber a good insulator .

Is wool an insulator?

Wool as an Insulator

Wool's natural structure makes it incredibly effective as an insulator. Each wool fiber is composed of protein molecules (keratin) organized into five follicles. These fibers effectively trap air, moisture and harmful chemicals.

Is iron a insulator?

Iron has metallic bonds which is where the electrons are free to move around more than one atom. This is called delocalization. Because of this, iron is a good conductor.

Is aluminum a insulator?

Aluminum has an emissivity of around 0.04. That means it radiates very little heat away from its surface, which is one reason why radiators aren't made from aluminum! Aluminum foil can be an effective insulating material because it doesn't radiate heat out into the environment.

Is plastic a insulator?

Plastics are excellent insulators, meaning they can efficiently trap heat — a quality that can be an advantage in something like a coffee cup sleeve.

Which of the following is not a conductor Mcq?

The correct answer is Distilled water.

Is magnesium a insulator?

The magnesium oxide insulator is used as an insulated core that wraps an exothermic wire and as a guide insulator that guide a metal wire.

Is Phosphorus a insulator?

- Phosphorus is highly reactive but it is non-metal and won't allow the electricity to pass through it. - So, because of the higher stability of the half-filled electrons in 2p orbital makes phosphorus as an insulator. - Therefore phosphorus is a bad conductor of electricity.

Is mercury an insulator?

Silver is a poor conductor of electricity while mercury is a very good conductor.

Is silk an insulator?

Silk isn't a great insulator. When exposed to a somewhat humid atmosphere it has significant electrical conductivity.

Which of following is not an insulator 1 a brick B Bamboo C brass D cardboard?

brass is a right answer

As it is an alloy.
