what is static electricity and is it harmful to human body? Why does hair stand up

The so-called static electricity is a static charge or a non-flowing charge (the flowing charge forms a current). Static electricity is formed when charges are accumulated on an object or surface, and charges are divided into positive charges and negative charges, that is to say, electrostatic phenomena are also divided into positive charges and negative charges. Positive static electricity is formed when positive charges are gathered on an object, and negative static electricity is formed when negative charges are gathered on an object. However, whether it is positive static electricity or negative static electricity, when an object with static electricity contacts an object with zero potential (grounded object) or an object with potential difference, charge transfer will occur, which is the phenomenon of spark discharge that we see every day. The expert explained:? Positive electrostatic radiation is harmful to human body, while negative electrostatic radiation is not harmful to human body? .

Static electricity will make our hair stand on end, which is a repulsive phenomenon. Attractions will make our hair stand on end, because static electricity and our hair are of the same sex, and we all know a common sense, that is, opposites attract and same sex repel. Generally speaking, no matter when, static electricity is always with us, but generally speaking, static electricity is mainly in autumn and winter, which is a relatively dry season.
