When the plastic coating around a cord is damaged, why does the cord become hazardous?

Question

anonymous · Answer

You probably mean an electrical cord, and it becomes dangerous becauseit becomes possible for electricity to flow from the conductors inside the cord through some external conductor -- like a piece of metal, or someone's hand -- to ground.  This flow of electricity may be damaging in itself, e.g. if it gives someone an electrical shock, or the heat of a large flow of electricity, in an unexpected place, may lead to a fire.
