"Hey guys"

This is the part where I beg for help.

I rarely ask for help from you gaylords, because the truth is, the majority of you are idiots.
Anyway, that's the flattery out of the way...

Physics - the subject of joy. I'm stuck on this question.

It's worth 3 marks. Anyway;

"The resistance of a length of bare uniform resistance wire is 30 ohms. The length of wire is folded into the shape of a square and the ends soldered together as shown below

(a picture of a square with an ohmmeter connected to it) - [URL]http://firestorm.staghosting.com/image.jpg[/URL]

What value of resistance would the ohmmeter read if it is connected as shown at the mid-points of opposite sides to the square?
(You may ignore the resistance of the ohmmeter leads)"

Cheers for any help people - I'm honestly at a loss.
And merm, if you claim it's 600 joules, I will hit you.

Yep, I now say I got 70-75%.
I don't think anyone has ever got an A as their overall grade.

Yes, it's the only real answer you can do anyway.

It usually has resistors but the wire should be the same, Biggles is right about the physics behind it as well. 7.5 ohms it is.

Though i bet the people in your family think the B-/C+ are "bad grades".

I'd better do the same.

And also - this parallel idea - are you sure?

It was actually McHardy but you get the idea.

Ah Highers, failed all my prelims, got predicted C for every subject.
Then got 3 As and 2Bs MWAH HA HA HA

Yeah, I'm really stupid at University even though I enjoy all my subjects. So much stuff to read, commuting and going to work... all takes its tole. I'm happy just to get a B-/C+ (which is about 70-75%, which was an A at Higher).

Mc Hard On


Like a McDonalds Erection?

BWAHAHAH!

Those unit tests were a bit silly, though they did allow me to flex my brain muscle as i came top of the class for half of them.

Pwnzerous, thats the best description for me in those days. Once you get to uni it all gets a bit more intense though, finding yourself having to read through numerous books just to grasp the basic concepts behind what the hell is going on.

:(

That's the right answer.

If it's in series it divided among them... if I remember, which I don't.

Hmm.

7.5 Ohms

Resistances in parallel. 1/15 + 1/15 = 2/15. Invert. 15/2 = 7.5

But then it's been about 10 years since I last did phyciscs or electronic engineering, so I take no responsibility.

Who got a Band 1 A at Higher Physics.

And I failed every single unit test... take that Mr McHardon.
