The energy that causes your hair to stay erect when you rub it on the comb can also annihilate electronic gadgets and cause explosions. To understand what is static electricity and its aspects, we first need to dive into the fundamentals of atoms and electric charge. This blog will help you understand the Class 12 Physics concept of Electric Charges and Static Electricity, Protons, Electrons, Neutron,and their nature.

Electrons are loosely held if we compare them to protons. As a result, the movement of charges will be limited to the movement of electrons. We know atoms are composed of electrons and protons. Therefore, it can be said that all matter is formed by electric charge. The charge of an electron equalizes the strength of the charge of an electron. When the number of protons and electrons equalizes each other in an atom, the atom is left with no overall, becoming neutral.
Electrons are very loosely held in matters. This reflects that a simple contact such as rubbing can also make them get exchanged.
When we rub two materials together to produce static electricity, one item loses electrons and becomes more positively charged, while on the other hand, the other material gathers the electrons and turns negatively charged. We should understand that the notions like unlike charge attract and like charges repel are applicable here.
Have you noticed when your hair stands out when you remove your cap from your head? If not, recall it now. You can do it as well. Static Electricity is produced here too. It happens like this; when we take out the cap from our head, the electrons are transferred from cap to hair, making your hair stand out.
Remember that materials with the same charge resist each other. This is what happens in this case. As they have the same charges, your hairs make efforts to repel each other as far they can.
The same happens when you rub a comb with your hair repeatedly. Moreover, you may also definitely rubbed the comb on your hair and then to the pieces of paper with a comb and become amazed by the attraction of paper towards the comb. The comb loses electrons when rubbed with hairs. This imbalance of electric charges produces static electricity and makes the comb attracts the pieces of paper.
