Human body charged
The body's volume resistivity is very low and can be considered as a conductor. When the human body wears insulated shoes or stands on an insulated floor, the human body can electrify through contact. The human body can also be charged by induction, and can be electrically charged by contact with other charged bodies. The most common is due to the clothes that are worn.
The object is charged. The common human body charging process is as follows:
(1) The process of people standing up from a chair or wiping a wall (the initial charge separation occurs on the outer surface of clothing or other related objects, and then the human body is charged by induction).
(2) The person walks on an insulating floor such as a carpet made of high-resistivity shelf material (the initial charge separation occurs between the shoe and the floor, and then, for the conductive shoe, the human body is charged by the charge transfer; for the insulated shoe, The human body is charged by induction).
(3) Static electricity when the outer garment is removed. This occurs when the contact between the outer garment and the inner garment is electrified, and the human body is charged by charge transfer or induction.
(4) Liquid or powder is poured from a container held by a person (the liquid or powder carries away a charge of one polarity, leaving an equal amount of charge of the opposite sex on the human body.
(5) Contact with charged materials. Such as charging when sampling highly charged powder. When there is a continuous electrification process, the highest potential of the human body is limited to about 50 kV or less due to charge leakage and discharge.
