I Wonder Why – Why Birds Don’T Get Electrocuted?


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.
