With two hands touching the wire, standing on the insulator stool, can you get an electric shock? Why?
Also not! If hanging in the air that the zero line, a line is over! Because the line is generally 220V voltage, zero line 0V, the formation of voltage difference! It will flow through your body
And both hands touch the fire line at the same time, the voltage difference between hands is almost zero. So no voltage, no electric current, no electric shock
No, because the electric shock must have a high current flowing through the body. Your foot is in the insulation, proving that the current does not flow from the hand channel.
Can't！ To current flows, need to have the potential, you are in contact with the fire, there is no potential difference between the two. You're on the insulating stool, with the land there is no potential difference!
