Power is generated at the powerstation, gets sent through cables to our house, through wires into my microwave. My microwave has a fault so the current goes down the earth wire into the ground but then where? Where is the ground connected backup to this circuit to complete the link and allow the current to flow??
In: Physics
you asnwered yourself with the statement
the circuit is closed by its ground connection since that effectively means the eletricity flows into ground.
what causes the fault to trip is the fact this power doesnt return tothe smaller circuit creating a huge diferential, this is detected by system like GFCDs and causes the breaker to trip
