Interesting Educative Questions by Elgaxton(m): 10:47am On Aug 26, 2009 |
I have always wondered [B]Why Do Birds Not Get Electrocuted When They Stand On High Tension Electric Wires?[/B] and after some research I came up with this answer from google search: The wire is not neutral - it is live. Birds do not get electocuted because they are not connected to earth and therefore do not complete a circuit through which the electricity can flow. Electricity takes the easiest route to earth, ie along the cable. There is no reason for it to take a detour through the bird if the bird does not form a shortcut to earth. But i still wonder what happens to us humans if we hang unto a naked high tension without having bodies earthed? Are we gonna survive or get fried up by high voltage? Please hear your views + your own questions. |

one thing we should realize is that there is no way you can explain anything relating to engineering especially electricity without a mathematical model. the structure of birds facilitates insulation and due to this reason the flow of current through a bird becomes very difficult. in other words since R = V/I, the resistance to current flow through the bird at that point tends to infinity because the current I tends to zero. do you know what is going to happen when a curious guy tries to be like a bird, he'd get pimped meaning barbecue. |
