In dry weather ... about electricity.

All the above phenomena are generally due to the principle of friction, which mostly occurs in wearing chemical fiber cloth clothes and dry winter. The charge generated by friction is unevenly distributed on the body, some places are positively charged and some places are negatively charged. Even different parts of the human body will have different charges. When you take off your sweater, shake hands or touch the door handle, places with different charges contact each other or the earth, which will produce a discharge phenomenon, that is, the electric shock effect.

Dry weather and less water vapor in the air are not conducive to the release of static electricity, which will increase the accumulation of static electricity and make the discharge more obvious. If the humidity of the air increases, the air can become a grounding conductor, causing the charged body to discharge.
