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
Circuit breakers work if there is a severe overcurrent in the circuit e.g. a shortcut.
If your lamp has a metal frame and a loose live wire inside touches the frame, you’d be grilled if you touch it. Now if we have a low resistance path, that’d ground the frame and short the circuit, the circuit breaker would flip and kill the circuit before anyone touches. This is what the ground wire is for.
