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

Answer Posted / senthil kumar.a

basically the current is flow b/w only a closed circuit.the
current is flow when circuit is closed. the birds are sit
either phase or netural . it cause the circuit is not
closed. so no current flow there, sometimes u seen the
birds are dead, at that time they wings are un fortunately
touch the any other line,

not birds only in case we r touch the any one line we
cannot get shock,
