Why dont birds get electocuted when they are on power lines?

In summary, the physical arrangement of power transmission lines involves multiple wires spaced apart, with typical AC voltages distributed between them. The reason for this spacing is to prevent a complete circuit and potential difference, which could result in electrocution for anyone touching the wires and the ground.

Maybe because charge passes through the powerlines and doesn't stay at one spot?

How are power transmission lines physically arranged? How many wires are there, and how far apart are they spaced? What are the typical AC voltages involved, and how are the voltages distributed between the wires? Why are the wires in the AC transmission lines spaced apart like that?

No... the circuit isn't complete. There is no potential difference. If, however, a man standing on the ground touched the same wires, he would be electrocuted, as the potential on the ground is zero and a potential difference existas across the man.
 

1. Why don't birds get electrocuted when they are on power lines?

Birds are able to safely perch on power lines because they do not create a path for electricity to flow through. Power lines are made of materials that are excellent conductors of electricity, such as copper or aluminum. However, birds' bodies are not good conductors, so the electricity is not able to pass through them.

2. Can birds get electrocuted if they touch two power lines at once?

It is possible for birds to get electrocuted if they touch two power lines at once, as this creates a complete path for electricity to flow through. However, birds are usually able to avoid this by perching on only one power line at a time.

3. Why do power lines not harm birds like they harm humans?

Power lines are designed to carry high voltages of electricity, which can be dangerous for humans to come into contact with. However, birds' bodies are built differently and are able to withstand the high voltage without being harmed.

4. Do birds build up a resistance to electricity from perching on power lines?

No, birds do not build up a resistance to electricity from perching on power lines. Their bodies are naturally able to withstand the voltage without any change in their biology.

5. Are there any dangers for birds perching on power lines?

While birds are generally safe perching on power lines, there are still some potential dangers. If a power line were to suddenly break or become damaged, the bird could be injured or killed by the resulting electrical surge. Additionally, birds may accidentally touch two power lines at once, which could result in electrocution.
