genuine question

Hi all I know a lot of people on this forum won't know this so I'm going to bring it up, potential difference.

Potential difference is voltage, so if I measure between live and a metal object will I get 230v. It is a difference in potential at the end of the day.

Minimal potential difference between feet. Electricity likes the path of least resistance. Offer the bird a nearby ground potential and you get a fried snack as the current wants to get to earth and the bird becomes the conductor

Why doesn't the electrical current pass through 1 birds leg and out the other and fry the bird

Now I know you're having a laugh pal.

Because the potential difference between the birds feet is minute as the birds legs are close together.

in actual fact, some current will flow through the bird's legs, as the bird is a parallel resistance to the wire it's standing on. however, the resistance of the bird's body is far greater than that of the cable between it's feet and so the current flow through the bird is negligible.

google resistors in parallel.

And of course Trev your right, a plumber taking the P.

Still, made me smile after a hard day!

Having thought about your question a little more I think the easiest explanation regarding the bird on the wire is that the electrickery is flowing up each leg at the same time and meeting in the middle, both currents being equal, one is not stronger than the other so they just kind of stand there butting heads and getting no advantage, were you to fly up and touch the bird with one hand only you'd die because the electrickery is only entering your body through one point and doesn't meet the opposing current coming the other way. Grab it with both hands and you'd be ok though.

I am of course taking the p.

on a similar note, andre previn should not sit on the wire because he's a good conductor.

Now your getting into advanced theory LOL.

Genuine question results in spasticated answers, thanks for the people that have positive answers so basically it has to be part of the electrical system

 

[trev]

The conductive part you're touching has to be connected to earth for current to flow. as per post 2 I believe.

 

[micknew]

Not trying to take the P Mick, are you new to the noble art of electrickery?

 

[trev]

And to be fair to us we're always up for a bit of sport, it's just your poor luck that you were it tonight. Don't worry though it'll be someone else tomorrow and pretty soon you'll be joining in with us. We don't mean to be nasty, it's all Tel's fault he made us do it

or to neutral.

So when you test across live and earth to measure voltage current flows or is it giving the current potential to flow
