so i have learned that potential difference always occurs between points which have some common node that is if you have two circuits which don't have anything in common there will not exist any potential difference between any two points my question is why do we get electric shock when we touch live wire because there is nothing common between distributed live wire and Earth and even if i check potential difference between live wire and Earth using dmm i get 0 volts so why do we get electric shock when there is no potential difference
