In experiments on electricity, namely conductors and non-conductors, we found that ordinary tap water is not a conductor, neither is sugar water, but salt water is. Then why do they say that when we are in the water we are not allowed to have electrical devices near us and we are not allowed to touch electrical wires with wet hands?
Answer
Pure, pure, distilled water is indeed not a conductor.
However, the water that comes from our bottles contains various salts and minerals – in small quantities, but that is enough. Water with such solutions immediately becomes a good conductor of electricity. Tap water also contains chlorine and other cleaning agents. It is therefore not pure water and conducts electricity very well. If your hands are wet from tap water, bottled water or rainwater, it is therefore very dangerous to touch electrical wires.
And even if your hands were wet with pure water, it is still dangerous. After all, dust particles or invisible dirt on your hands will dissolve in that water and make it impure, so that it will suddenly start to conduct and still become dangerous.
