Background

Static electricity is a static or non-flowing charge (a flowing charge forms a current). Static electricity is formed when charges are accumulated on an object or a surface, and the charges are classified into two kinds of positive charges and negative charges, that is, the static electricity phenomenon is also classified into two kinds, i.e., positive static electricity and negative static electricity. When positive charges are accumulated on a certain object, positive static electricity is formed, and when negative charges are accumulated on a certain object, negative static electricity is formed, but no matter the positive static electricity or the negative static electricity is, when an object with static electricity is contacted with a zero potential object (a grounding object) or an object with a potential difference, charge transfer can occur, namely, a spark discharge phenomenon is seen daily.

In dry and windy autumn, people often encounter the phenomenon that when people sleep without clothes at night, crackling sound is often heard in the dark and is accompanied with blue light; when the hands meet with each other, the fingers feel pricked pain like a fingertip needle immediately when contacting the opposite side, so that people feel frightened and discolored; when combing in the morning, the hair will often "fly".
