A bird sitting on a naked wire carrying current feels quite
safe, but when the wire between his feet is cut and joined
by a very long loop of wire, the bird dies. Why?
Answer Posted / khan
because when a bird is sitting on naked wire its potetial
difference is zero, when there is no pitential difference
the bird does not get current but when wire between his
feet is cut and joined by a very long loop of wire,the
potential difference is created and current passes thorugh
the bird and hence it dies
