why, when birds sit on transmission lines or current wires
doesn't get shock?
Answer Posted / sewagudde
its quite simple, air acts as an insulator and thus there
is no path for current flow to earth. however when it gets
in contact with 2 lines, a potential difference is created
resulting in current flow through the bird's body.
