Why, when birds sit on transmission lines or current wires doesn't get shock?

Why, when birds sit on transmission lines or current wires doesn't get shock?
by

1 Answer

Answer :

It’s true that if birds touch the single one line (phase or neutral) they don't get electrical shock... if birds touch 2 lines than the circuit is closed and they get electrical shock. so if a human touch single one line (phase) then he doesn't get shock if he is in the air (not touching - standing on the ground if he is standing on the ground then touching the line (phase) he will get a shock because the ground on what we standing is like line (ground bed - like neutral) । and in the most of electric lines the neutral is grounded..So that means that human who touch the line closes the circuit between phase and neutral.
