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
a Ground wire is basically a safety mechanism for a circuit to safely off load any current that it couldn’t discharge thru the normal circuit.
without a ground wire this current will look for the next best conductor which could be the poor sap that touched it. the Ground wire will also ensure that in the event of a circuit failure, the discharge thru itself will cause the breaker to trip(as due to the loss, current will be way higher than its safe and if not interrupted it could burn the wires and cause a fire).
