Why does a bird not get an electric shock when it sits on a live wire?
● The Two wires in an electric post are kept in different potentials.
● One Wire, which we call life, will be at a high potential and it is a Phase wire. The
other wire is neutral and its potential is zero.
● When a bird perches on the live wire, her body becomes charged for the
moment, it’s at the same voltage as the wire. But no current flows into her body.
● But if a bird accidentally touches an electrical “ground” while in contact with the
high voltage wire, she gets an electric shock.
● A ground is a region of approximately zero voltage. The earth, and anything
touching it that can conduct current, is the ground.
