Why is a bird sitting on a high-voltage transmission line not electrocuted? Why does it get electrocuted when it touches another wire?
A bird sitting on a single wire is not electrocuted because both its feet are at the same potential, meaning no potential difference exists between them. Without a potential difference, current does not flow through the bird’s body. However, when the bird touches another wire (of a different potential), a potential difference is created between … Read more
