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 / 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

Answer / sanju
In the first case it feels quote safe, because the feathery
pad under hid feet is a poor conductor and hence the
current, talking the path of least resistance, flows
straight along the wire and the bird is unaffected. In the
second case the resistance of loop becomes considerable and
is of the same value as that of feathery pas. So a part of
the current passes through his body and it dies.
