"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.

Where does Bigfoot come into this post?

Writing answer of seperate bit of paper.

How much space have you got to write in the answer, or dont you do that at A-level?

Not really.

It's a given.

Do you even know what Sasquatching ®Sasquatch industries 2003 is?

I think it’s very hard to determine that out without having it set up in front of you.

29.5 ohms.

It loses 0.5 due to heat pressure and sasquatching.

I think the answer is EIGHTY EIGHT MILES PER HOUR!

The gayby forum posted that before i was finished typing

As there are no components the resistance will stay the same wherever the ohmmeter is set on the circuit.

You do sometimes, theyre testing your knowhow just as much as asking for a calculation. They do it in Uni all the time in Physics.

This only happens if there something to interfere, i.e. a resistor, but theres nothing in the cicuit bar the ohmmeter
