What happens to charges when you comb your hair?
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.
What is the charging process being performed when a you comb your hair such that the comb will become a charged object and will attract piece of a paper?
Charging by induction. The comb has become charged by friction, acquiring an excess of electrons.
Why do combs attract hair?
This happens because the charged comb induces an opposite charge in the paper and as opposite charges attract, the paper sticks to the comb. 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.
What happens if you comb your hair and it becomes negatively charged?
If you comb your hair and the comb becomes positively charged, your hair becomes negatively charged A negatively-charged rod is held near an aluminum can that rests on a dry wood table.
What happens when you comb your hair with a comb?
Depending on the material of the comb, either the comb will be positively charged and the hair negatively charged, or it could be the other way around. Since opposing charges attract each each, the hair then is attracted to the comb.
Why does a comb have a positive or negative charge?
The charge created by the extra electrons on the comb drives the elctrons on the near side of the paper to the far side, negatively charging the far side. The lack of electrons on the near side create a positive charge on that side. The positively charged side of the pieces of paper are attracted to the negatively charged comb.
Why is hair a conductor of static electricity?
So in front of comb, hair is an conductor.. So on conductor there are presence of free electrons that’s y it’s resistance is less than comb so while rubbing unwanted electrons of hair goes in comb so hair gets positively charged…. I hope you understood….
What happens if you comb your hair and the comb becomes positively?
The hair gets electrons from the comb, dropping the comb with a lack of electrons and a positive charge, the hair momentarily has an abundance of electrons and a negative charge. When we bring the comb near hair after combing then attraction happens, therefore, hair become negatively charged.
Can a comb have a positive or negative charge?
If however, the comb is made out of polyurethane, or another unlisted material with a higher positive charge affinity than hair, then the hair would leave with a negative charge. Also, if your hair is wet, soapy, or has other contaminants in it, this will have a great affect on this as well – just keep that in mind!
Why does your hair have a negative charge?
This makes your hair postive (lost electrons), the comb negative (gained electrons) and anything near the comb will be attracted if it is positive (lacking electrons relative to the comb), like water. Another example is when you rub socks on carpet.
What happens to electrons when you comb your hair?
When you comb hair or perform another similar activity, the extra electrons that are just sitting in your hair are transferred to the brush/comb. This makes your hair postive (lost electrons), the comb negative (gained electrons) and anything near the comb will be attracted if it is positive (lacking electrons relative to the comb), like water.
