"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.

Then try to say that if the wire is bent this may effect the resistance, I know I’m contradicting myself but I remember my coursework last year about if the wire in not straight there is a tiny bit more resistance.

Yeah.... YEAH!

I would have got it if i done physics, but chemistry was just too superior.

I did SG chemistry and preferred it to physics.

So I took physics at higher.

...?

Must be hard to know your getting dumb, may I suggest eating cake, its life back alley.

Who got a Band 1 A at Higher Physics.

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

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.

That's the right answer.

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

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.

Mc Hard On


Like a McDonalds Erection?

BWAHAHAH!
