Why birds dont get electrocuted when they sit on power lines?

Birds do not get electrocuted when they sit on power lines because they are not grounded. Electricity always seeks the path of least resistance to the ground, and since birds are not touching the ground or any other conductive material while sitting on power lines, the electricity does not flow through their bodies. Additionally, birds have a high resistance to electricity due to their feathers and the air gaps between their body parts, which further reduces the risk of electrocution.

Birds don't get electrocuted when they sit on power lines because they are not grounded. In order for an electric current to flow, there must be a complete circuit. The power line provides one side of the circuit, but the bird's body does not provide the other side. The bird's body is not touching the ground, so there is no path for the current to flow.
