By the way, if you feel the urge to conduct such an experiment on your own mortal carcass, remember one thing - touch the wire with the back of your hand - so you can at least quickly remove your hand, because under the action of the current, the muscles contract and the effect will be minimal in time.
You will be electrocuted. If the voltage is weak and the current is weak, it will be unpleasant, but if the voltage is high and the current is strong, it can simply kill. And you will lie next to the wire, cold and lifeless, with traces of the effect of the current on your skin, and witnesses will hardly express approval of your act.
Anything can happen here: the wire can be energized and the current will pass from your hand to your leg. You can prick yourself once the wire is barbed. A guard may come and tell you not to touch the wire, because it is energized. You may want to eat and then forget about the wire.
