In commercial power grids, one side of the generator is connected to ground (earth). So, when one is in contact with earth, they complete the circuit.
BTW, the rubber soled boots are only effective to a particular voltage. After that, the rubber insulation will break down and the person will get shocked anyway.
Rubber acts as a resistance from Line to the Ground. As long as the resistance is high enough, we won't get shocked. But we can still get shocked if the voltage is high enough to overcome the resistance or whatever is isolating us from the "ground".
The idea is to get isolated from ground with as much resistance as possible. Try a plastic stool and step on it and touch a live wire assuming it's a household supply voltage (110Vac to 240Vac). You won't get shocked.
While you are touching the line, lift off one of your feet from the stool and touch it barefooted to the ground, you will get shocked because you completed a line to ground connection.
Rubber absorbs electricity, but if it absorbs too much, it will burst into flames
this is truly a billion dollars question,from edison to hawkins so many great minds tried to figure it out but still no satisfactory answer.
please explain the reason
