Oh it sure does apply to humans. In HSE, you are taught that if there's live voltage on the floor, you don't walk across the floor else you create a potential difference and get an electric shock. You hop like a bird to safety.

My brother lets them know... The bird is wise and always take safety precautions following SOP... They arent like human biengs...... Some human biengs behave lesser than goats, like when a linesman go on a high voltage ⚡ witout standard insulated gloves, forgetting the ladder hes on is a path to the ground.... Seens alot of them roast when there a current flow..... I just do the investigation and forget to give them a minute silence

[quote author=Drehilton post=54936385]Am really surprised you'll speak like that...it's very insultive.
Yes,you may know the answer because that's your field.you need to understand that it might not be others and that does not make them illiterate.Instead of you to simply explain in common terms that others might understand:you're displaying I.T.K
SIMPLY PUT,Birds don't get electrocuted because there is no potential difference.MEANING:Difference in energy.
Before something or someone can be electrocuted...current must pass through from a source to a conductor (which can be cable,man,anything) then to the earth.That would be a complete path for current to pass through.
1)The bird lands on the cable with its legs at the same time.If done otherwise the bird would be electrocuted...as the difference between landing with leg1 and leg2 would cause p.d
2)The bird is standing alone and it's upright,thus current cannot easily flow from down to up...that is why bats do get roasted as current tends to flow easily downwards due to gravitational force
3)The bird is standing on the same wire..it has the same flow of current with no potential difference...if it's across two wires...that is suicidal.[/quote

you call him ITK? you should be ashamed of yourself for siding with stark nonentities.

the OP asked a question that requires a professional response, what business has a total daft in responding when he knows the question is not within the purview of his knowledge? why not leave it to the pros and wait for questions within his/her grasp?

you people had better stop championing mediocrity!

Different explanations

Interesting, very interesting....

BlakKluKluxKlan:
I believe very strongly that birds' claws have special insulators that protect them from electrocution.

Birds with the strongest claws or insulation sitting on live wire will still be electrocuted if the birds touch any nearby object!

Mbok, we owe our people a duty to protect them not just reactively but also proactively. So biko do all you can to protect them.. I think a comprehensive risk assessment before the job is far better than an incident investigation or minute silence.
My two cents o

Ebookmathswaec:
This is not true at all!

We are talking about thousands of voltage here which is capable of bleaching insulation in insulating materials!

Am afraid it's very true. Birds are not elecrocuted because dere is practically no blood in dere legs and even d bones are hollow. The only reasons other animals are electocuted is because of d presence of blood. Even d highest voltage of electricity cannot travel through a very very good insulating material.

You're wrong!

Insulators like plastics, rubbers, fur, air, etc will conduct electricity if they are subjected to a very high voltage. The insulation will be bleached.

For the birds, they have blood running through all parts of their body.

Can a risk assesment prevent an accident when more than 90% of accident occurs frm behavioural patterns of workers, always wanting to take shortcuts and bypass procedures in other to meet yp with thier priority.... Have u ever asked yourself why the best safety companys o the world with all risk assessment said and done atill record accidents......


So men safety has gone past risk assessment and what not.... Dats for nebosh exams and the rest... In the real world, its different... Work with reality my broda

Yes, IMO risk assessment prevent accidents. Assessing risks thoroughly provides a rational basis for safe practices and behaviour. No it's not NEBOSH lol...it's real time experience. It's human to want to take short cuts. It's my duty to prevent you from taking it. For instance, how can one bypass a lock out tag out system or PTW system designed in such a way it stops accident even before they occur?

There Is A Convenant Between Electricity And Birds

I can't still believe that an average student on nairaland can not give a valid answer to this simple question.

Scientifically: Ohms law states that the current passing through a conductor from point A and to point B is directly proportional to the voltage or potential difference across the point. Provides the resistance remains constant including temperature

NOW THE ANSWER:

Electricity flows along the path of least resistance. Birds don't get shocked when they sit on electrical wires because they are not good conductors of electricity. Their cells and tissues do not offer electrons an easier route than the copper wire they're already traveling along.

Their feet is insulated. You could see it been removed with hot water when kill.

does dat mean human can't hang on live wire with one hand on air and survive

Your hands contains free radicals or electrons that can conduct heat and electricity. Once u hang ur hands on 11000v conductor you have completed the circuit. And ur name will be sorry

Lwkmd!

zuby4real10:
birds legs are fully dried with out a single blood in them that's y they are not sensitive.

I don't agree with that.... There is an insulator/rubber like tissue covering their leg.... If you are conversant with killing hen, you will knw about this...

Wow I love this question, the best linesman is the bird.... Reason the bird can't get electrocuted while on the line is because there is no interruption of flow of electricity from one point to another, but let assume the bird hang on a line and mistakenly the tail touches the pole, channel iron or anything that goes to the ground as earthing, he get electrocuted immediately..... Same with human being,if you get suspended to a line without touching anything connected to the ground you won't get electoruted, cause flow of electricity is not interrupted and our body also has electrons......

sod09:
mention...pls don't tell me about the birds that transform to human oo
yes bird are likely to be electrocuted but not with there legs.
inshort almost impossible cos the fur can't conduct electricity

I am really surprised and dismayed from the response I see from Nairalander regarding the answer to this question cos it is a reflection of inability of average science student to correctly analysis a simple scientific phenomena .I weep for future of science and technology in this country
Answers:
For current to flow between two points along a conductor ,potential difference must exist e.g Live and neutral (220v and 0v).
The bird on the sitting on the power line is touching points that have the same potential difference(same voltage) on the line so current cannot pass through it. For the bird to get electrocuted ,the other part of it body must touch lower potential part of the line eg Earth or ,neutral line .
This is a principle of potential difference .

are u telling us that if u put on a slippers n touch a live wire it will not electrocute u?

Dude,google dis tin nw. Bird don't have blood in their legs. Nd dat also contribute 2 d reason why dey can fly nd humans can't. Dere legs are bloodless and hollow. They practically have no mass in dere legs

. Nd dude all doz insulators u listed isn't wat am talkn abt. No matter d voltage a very strong and durable ceramic protective wear will do d job. Trust me,if nt hw are electricians able 2 handle doz kind of power lines?

lol...too much of game of thrones

Have u ever killed a chicken before
If u did u will notice while cleaning the thing d leg u will have to remove a plastic like skin to expose d flesh.
All birds have this plastic waheva which insulates dem

Allwility:
I think that's because both claws perch close enough on the same wire so there's no potential difference. No potential difference means no flow of electrons and so no electric current.
However, if a part of the bird touches a second wire, the circuit becomes complete and electrocution occurs.

Thanks, you got it right!.....

I nearly became surprised! As big as nairaland is no one knew the answer to such a simple question.
Thank you for your correct answer. My career is electrical.

idris4r83:

Absolutely. It won't shock you because I do it all the time. Just ensure that you don't touch more than one wire at a time.

Ebookmathswaec:
Insulation of some insulating materials is bleached or destroyed when a very high voltage passes through them. In other words, insulators like fur, plastics, rubber, air, etc can conduct electricity if the voltage is high enough!

I can remember that we were taught those days.
I think the voltage at which an insulator conducts electricity (where voltage exceeds internal resistance) is called threshold voltage or conductive voltage.
It's been a while tho
