Pure water has a very high resiivity. If phase and neutral are dipped in water an insulated container there will not be a short irrespective of what metal the wires are made of.
If the phase wire is dipped in a pond of water in the ground, it will be grounded, again irrespective of the metal.

Assume that phase is in contact with the pond water. So normally electricity is being earthed. Now assume a person is in the pond at this time. There can be two cases.
1. The person is swimming. That is, he is just immersed in water and no part of his body is in contact with ground.
2. The person is immersed in water, but his legs are touching the ground. As if he is standing in waist height of water.

I am pretty sure, the person will not have the risk of electric shock in the case 1.
But what about the second? Considering the difference in resistivity of human body and water, what exactly will be the outcome?

Thank You sir. That clearly wiped off my doubt 😀
