And part 2: as soon as the electrical current is removed, does the water become immediately safe to touch again?
In: Chemistry
Electricity is dangerous to humans when human bodies are a part of the electrical circuit. If an area of high voltage finds a path to ground through a human body, that human will be hurt by the electricity.
Water that is electrified can be dangerous because water conducts electricity better then air. Say you have a puddle of water on a rubber floor. On one end of the puddle, there’s a wire with high voltage, on the other end of the puddle is a human touching the ground and the puddle.
The electricity flows from the wire through the water, through the human, to the ground. Human gets hurt in the process.
After the cable is removed, for a brief less than a nanosecond. That electricity still flows to ground trying to reach equilibrium. Once it does reach equilibrium it stops flowing.
