What would happen if a human were to touch an electrical wire just as the birds do?
Would it be any different if we had both hands touching compared to just one? What if we touched different wires with our hands? Sounds like you're ready to dig deeper, Bianca! Search the internet for 'conduct electricity' or visit your local library! Let us know what you find out! It's all dependant on the situation. It's just a natural rule that electricity wants to get to the ground to minimise electrical potential energy , and it wants the easiest path to that. If you're touching an electrical wire regardless of one or two hands and you're standing on the ground, your body will be a conductor and create a path for electricity to get to the ground.
Thus, you will experience some sensational form of electricity. In other words, you'll only get electrocuted if the current flows through you. This means that you must be in contact with a voltage source at one point and the ground or a lesser voltage for the current to flow through you. Birds do get electrocuted but on a negligible scale.
Even if it is assumed that no current flows through the bird's body though current does flow on a negligible scale as copper wire does have some resistance even if it is unobservable. At a constant voltage V bird's body would act like a capacitor A device that store charges of capacitance C. If this charged bird sits on other objects like branch of tree which is neutral object connected to Earth, electrons accumulated in the bird's body would flow to the Earth giving the bird a tingling shock.
However bird being so small a object, it would have very small capacitance thus less charge accumulated on it. This question was asked in. It sounds like you know a lot about this topic!! Thanks for sharing this information with us!! I couldn't complete my last sentence as my mobile malfunctioned. We're sorry to hear that, Wonder Friend! Luckily, there are many more Wonders to learn from!
I have 2 questions! As I understood, there are 2 main reasons why birds don't get electrocuted. The first one is they offer more resistance than the wire and the second is that they don't represent a difference in voltage. So my questions are: What happens with the voltage of the bird itself? I doubt the bird has 35, volts on it. So, when it touches the wire, there is not a difference between the wire and the bird? And second When the bird touches a second wire or ground, there is a difference of voltage and it gets fried.
But, what happens to the first point? The bird still represents a major resistant for current than the wire, so why doesnt the current in both wires bypass the bird and continue on the easiest path? It is a fact that the bird does not sits upon high-tension wire i. At this very high voltage, electrons rips off from the surface of the wire creating a cloud of electrons and charged ions around the high-tension wire. If bird try to perch upon this wire, it would get a nice-tingling shock in form of sparks from the electron-ion cloud. This is called "Corona discharge". There are several instances where a person comes accidentally close to high-tension overhead wires over train, this person would get electrostatically attracted to this wire and baked alive.
This happens in overpopulated areas of Africa and India where due to lack of space, passengers climb up on the roof of the train. Hello, Pepe!! It sounds like you have put a lot of time into this topic! We encourage you to take a Wonder Journey to discover the answers! This is completely wrong teachings. The bird does not get electrocuted because the bird is the same potential as the wire it's perched on. Hard to believe that this is the first Google result.
Electricity travels on the outer surface of the bird and sees no current through it's body Michael Faraday presented this with the Faraday cage On higher voltages there is an electrical phenomenon called Corona which buzzes as the wire throws electrons off. This irritates the birds. This is why you don't see birds perched on lines above 20, volts. I'll finish with saying I'm a journeyman lineman and I work at 5 voltage electricity every day of my life.
I completely agree with you. It is "search engine optimization" where if a site pays higher bucks money than others then that website "appears high on the list of results returned by Google". Thanks for your feedback, Blake! Great to know it's from a professional like you! We think we are essentially saying the same thing, but we did add a sentence to help clarify, based on your explanation. Good connection, Princess! We hope you enjoyed this Wonder. What is your favorite kind of bird? Hey there, Wonder Friend! Birds are capable of getting shocked or electrocuted, just like all other animals.
However, we hope this Wonder helped explained how they are able to sit on wires without being shocked. You're very welcome, Audrey! Hi, vasu! We're glad you liked this Wonder! Sometimes it helps us to read the Wonder again. We also encourage you to keep exploring this topic at the library and online! At the work sites it is apparent to see earth wires are connected to a conductor exposed copper then lead to grounding. My question is , Why this earthling not a reason of shock and if ground failed copper would be a conductor.
What is neutral?
Why copper using for grounding of electricity. We're glad this Wonder relates to your work! We encourage you to keep researching your questions at the library and online! My professor gave me an assignment. This is the question: Birds have been known to perch on volts bare transmission line without apparent harm. Is this because of the very dry nature of their feet?
So far, I haven't found any answers about their feet Welcome, Jan!

We're glad you stopped by Wonderopolis to help with your assignment! We encourage you to embark on your own Wonder Journey to discover more about this topic, as well! We're sure you can discover all sorts of interesting facts by researching your questions online and at your library! Hi, David! Did you know January 5th was National Bird Day? This was a perfect Wonder to explore! Thanks for joining the discussion, David! Isn't it crazy that birds can sit on the power lines? Hi, Dhanvantha!
Thanks for exploring this Wonder with us! Birds are not good conductors of electricity which is why they can sit safely on the wires.
I just saw crow got electric shocked and fell and died this morning. I wonder why only this got shocked among others.
I'm a little confused I didn't think so it touches the other wire. That's so sad! He could have died from a variety of reasons. We're sorry you had to witness that. Hopefully your day got better! Your post seems a bit misleading. You say they don't get shocked because they aren't good insulators, but later state that if a bird could touch the ground at the same time they would most likely get shocked If your first statement is true, your second would not likely matter. If the insulation of a bird was why it doesn't get shocked, the ground would not change that.
I'm an electronic tech. There are many reasons why birds would not get shocked.
If a bird could touch two lines or any other grounding source they would certainly be shocked at a minimum. Electrons follow the path of least resistance. If the bird touches another source, it would then be the path of least resistance. If two power lines happen to both be exactly the same, it might not, but if one line is v and one line is v, you could have 10 v go through the bird. Amperage is really what kills, not voltage.

Most power lines have tons of amperage and for a human a single amp through the heart could kill you. So there's really only one reason why a bird doesn't get fried. A bird sitting on 35,V wire has a potential of V but no potential difference. Current flows in presence of potential difference, not on potential itself. So it first case as there is almost no potential difference so almost no current would flow through it.
In the second case as the bird have a potential difference of 35,V : huge amount of current would flow through it and be roasted alive. Both of your statements 1st and 2nd are true. I will clarify your doubts. It is true that bird is poor conductor but its a relative term. It is very poor conductor when its compared to metals,graphite but it is an appreciable conductor when compared to plastic articles, PVC pipes polyvinyl chloride and Bakelite used in switches for insulation.
Bird does have some electrolytes present in the body to allow some conduction. Second clarification, Volt is used to measure electric potential and Voltage is used to measure potential difference and both are measured in SI units V,Volts. Current flow in presence of potential difference not on potential itself. A bird sitting on 35, V wire have an electric potential of V but no.
Thanks for your feedback, Grant! We value your additional information. In the Wonder Text above, we actually state that birds are not good conductors, not insulators. We recently had an engineer review the information and found that it is still accurate. Thanks, Wonder Friend! I Wonder if anyone has ever been able to research that before? Great thinking, Rishi! It's called Corona, and yes they can feel it. It feels like your skin is catching fire. Excites your nerve endings. This is why you don't see birds on extra high voltage lines Lineman work on the lines from helicopters or climbing out on the line using a Faraday suit to keep the burning sensation at Bay.
I liked the blog because it taught A LOT about how birds don't get shocked. Well, anyways I like how it made the birds music notes and I loved the music in the video.

Thanks for giving so much information Wonderopolis! Hi Faith! Hi Jacob! Your head exploded?! Ugh oh! I didn't like the video when it made the birds into music notes. The video was way too short, and the video didn't tell me or show me if birds get shocked while sitting on electrical wires. Hi there, Evey! Thanks for sharing what you liked and didn't like in our Wonder of the Day! We have lots to choose from, so perhaps you'll find your favorite soon!
I learned that birds can't get shocked on the wires because it can't go through their body. I was surprised to hear that if it touched the ground, we would get electrocuted. I want to now more about how it works. I wish I was a bird so I can sit on wires too! Thanks so much for sharing what you learned with us, Lilian! I learned that birds don't get shocked on wires. I was suprised that birds don't get shocked on the wires. I want to know more about power poles. I learned that birds do not get shocked while sitting on wires.
I was surprised no bird has been shocked. I want to know more about birds and what they do every day. I love doing these things because they are fun to do. I learned that birds don't get shocked. I was surprised that the birds looked like music notes. I want to learn more why people would get shocked and birds don't!
The music sounds cool!! I learned that birds are bad conductors of electricity.
I was surprised that there was no voltage difference. I want to learn more about how so many birds can be on at the same time. I thought that it was cool how birds don't get shocked on the wires. I was surprised by that. I thought they would get electrocuted if they touched the lines. I want to learn more about power lines. Hey hey hey! I'm back, anyways I thought the birds didn't get shocked because I thought there was rubber surrounding the wire, that's what I thought was protecting the birds. We're thrilled that you're here, Carlos! Thanks for sharing what you learned with us and what you already knew, too!
