Why a nylon or plastic comb gets electrified on combing dry hair or on rubbing?

Plastic comb is a poor conductor of electricity so they contain static charges. While rubbing due to friction these static charges gain electric and gets electrified. Wheras metal like spoon does not contain static conductors as they are good conductors of electricity.

Why does a plastic comb rubbed with dry hair attracts the bits of paper?

Initially, the comb is electrically neutral. So it has no effect on the tiny pieces of paper. When the comb is rubbed on a dry cloth, it gets electrically charged. This charged comb exerts an electric force on the tiny pieces of paper and attracts them.

What happens if a plastic comb is rubbed with dry hair?

When a plastic comb is rubbed against dry hair vigorously, then there is a transfer of charge taking place between the two. As a result, both objects become charged. While one becomes positively charged, the other becomes negatively charged. A comb moving through dry hair gets electrically charged.

Why a comb gets negatively charged on rubbing with dry hair?

A plastic comb when rubbed with dry hair gets charged. This is because the electrons present in our hair particles move to the comb and the comb has excessive negative charge which means that the comb has net negative charge. The charge remains static as there is no conducting medium for it to move.

Why does nylon or plastic?

Nylon is a strong, stiff engineering plastic with outstanding bearing and wear properties….Strong, stiff engineering plastic often used to replace metal bearings and bushings.

SHEET	Dimensions: 12 in x 12 in – 48 in x 120 in
Thickness: 0.031 in – 4 in Note: Type 6-Cast and Type 6/6-Extruded Sizes Vary

Why does your hair stick to a plastic comb?

If you comb your hair, for example, electrons leave the atoms and molecules in your hair and travel to the plastic comb. The comb, covered in negatively charged electrons, becomes negatively charged as well, and your hair is left with a positive charge.

How does comb get charged when rubbed with hair?

When a comb is run through your hair charges pass between your hair and the comb, so the comb becomes charged either positively or negatively, and the hair oppositely charged. The charges move from one insulator to another on vigorous contact (i.e. by rubbing) to produce the two oppositely charged objects.

Which would give up electrons If hair is combed with a plastic comb?

Is a plastic comb an insulator?

If you hold a plastic comb in your hand and rub it in your hair it will get charged. Plastic is an insulator, whereas metals are good conductors of electricity. When a plastic comb is rubbed on our hair, it acquires static charges, which do not move.
