Q. Why does a bird sitting on a high tension electric wire do not get electrocuted?
Answer: It does not form a closed path for the flow of electricity
Notes: Birds can sit on high-voltage power lines without getting electrocuted because they are not good conductors of electricity. When a bird sits on a wire, it doesn't touch the ground or anything in contact with the ground. This means there is no potential difference for electricity to flow. However, if a bird touches a power line and equipment or other metal that is grounded, it gives electricity a path to the ground, and the bird could be shocked. Birds could also be shocked if they flap their wings and touch another electric wire with a different voltage. Birds can also be in danger if they sit on the wooden poles supporting the wires. These poles are buried in the ground, so they have a low electrical potential. If a bird were to sit on the pole and simultaneously touch a wire, the current would flow from the high potential wire through the bird's body and into the low potential ground.
