Question

(2)a bird sitting on a bare high power line does not get an electric shock, but if a man standing on ground touches the same line he gets a fatal shock.

Answer 1

Answer:

The circuit between the bird sitting on the live wire and the earth is not complete and no current flows through the body of the bird which remains safe.

However, if a man standing on the ground touches the same wire, the circuit to the earth is complete through his body and a heavy current passes through his body, causing a fatal shock.

This is the reason why a bird sitting on a bare high power line does not get an electric shock, but if a man standing on ground touches the same line he gets a fatal shock
