I was reading about current electricity and some how I came across the idea that a circuit of no earthed point will not cause any electric shock.
I wonder if it is right cause if it is, why do we need an Earth wire in our appliance.
I am also suspicious because if the circuit is not earthed, then there must be a non-zero potential on any point of it, so why is there no electric shock? Given that the person is standing on the ground and has zero potential, a p.d. should arise.
