ok... try another way :)
its true that if birds touch the single one line (phase or
neutral) than 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...
there is more technical explanation, but I think that I wont
be able to explain it in English and without drawing...
so I hope that u got some kind of understanding... :)
