why it is possible for a bird to perch on a high voltage wire without being electrocuted​

Answer 1

Answer:

why it is possible for a bird to perch on a high voltage wire without being electrocuted

because they don't have muscles and blood in their feet

Explanation:

that's why it Is possible

Answer 2

Explanation:

The reason the bird is not electrocuted is due to some facts about circuit:

1. Completeness of circuit- This circuit needs to be complete in order for current to flow. The bird standing on only one wire has not completed the circuit.

2. A potential difference: Another factor deciding the direction of flow of current is (electric) potential. Current always flows from a higher potential to a lower potential. In other words, it can be said that electrons flow from lower potential to higher one. (the direction of electric current is opposite to that of the electrons). So, we need the potential difference for current to flow. The bird standing on only one wire has no potential difference.

3. Path of least Resistance- Factor that decides the path a current will flow in case of parallel paths is the (electric) resistance offered by the path. Current will always flow in the path that offers least resistance. The leg of a bird has high resistance. It has no potential difference as both the legs of bird are touching the same wire at same constant potential. If the bird would touch the ground while sitting on the wire or flap its wings and touch another electric wire with a different voltage, then it would get shocked and likely die by electrocution. While in the other hand, the Bird that touches two wires with it wings at the same time will get electrocuted because it has completed a circuit and the its feathers created a potential difference.
