In the dry season, take off the coat and then touch the metal door handle is to be electric shock, which is because the discharge and discharge it or because there is current,
People at this time feel the electric shock in the end is how is it?
Precipitated discharge is explained by the body by the friction generated by a large number of charged particles on the earth to form a static high pressure, when the fingertip contact with the metal gate when the discharge phenomenon is the initial stage; and the discharge that is high to low potential release Electronic to the end of the state of the process; the two are not contradictory.
As the dry season, the body and the earth insulation resistance increases, therefore, due to take off the coat friction generated by static electricity, can not form a loop with the earth, the body at this time to capture the electronic and ground potential difference, then, if you touch the metal door Handle, the electron will be released, "electric shock" after the body and the ground potential difference will be neutralized to reach a balance.
