I understand if we touch the wire and were are on the ground it creates a complete circuit. So we get electrocuted.
But how does the ground or earth wire works, so that we don’t get electrocuted?
In: Engineering
Current likes to take the path of least resistance
You’ll usually only find ground wires in machines with a conductive casing (or has a lot of conductive material present). All of these metal pieces are connected to the ground wire
Now the purpose for this is, if there was a loose wiring in the machine and it accidentally touches the conductive casing and you proceed to touch said casing, you will create a short between that wire and the ground you’re standing on and thus getting shocked.
However, if the ground was connected to that metal casing you won’t feel the shock as it’s easier for the current to flow through the ground wire than your body as your body has a much higher resistance comparatively
