Why does a bird not get an electric shock when it sits on a live wire?

Why does a bird not get an electric shock when it sits on a live wire?

A bird sitting on a live wire will get a shock only if the electric current passes through its body.

We can contrast the flow of electrical energy through a body to the flow of water.

Like in a water flow, electric powered current always flows from a higher promise level to a smaller potential level.

The two wires in an electric mail are kept in different potentials. One cable, which we call reside, will be at a high potential, and it is the stage cable.

The other cable is neutral and its promise is zero. On sitting on the live wire, the bird's potential will furthermore be increased to the same potential as the wire's.

If it comes in communicate with the neutral cable, a present will pass through its body from the reside cable to the neutral cable.

Then the bird gets an electric shock.

The bird can sit on the reside wire without getting electric shock as long as it doesn't feel the neutral wire.
