Question. . .!

Question: why, when birds sit on transmission lines or current wires doesn't get shock?
Its true that if birds sit on single phase transmission line they do not get sock but is they touch two lines then the circuit is closed and they get electrical shock.

so if a human touch a single one line then he doesn't get shock if he is standing in the air. if he is standing on the ground then touching the line he will get a shock because the ground on what we standing is like a neutral and in the most electric lines neutral is grounded so that means that human who touch the line closes the circuit between phase and neutral.
