"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.

Isn't Higher = AS and then Advanced Higher = A2?

We have an image!

I think this is right Forza, the wire being bent has no effect and theres nothing to change the resistence as there apparently is no voltage and no current, so its still 30 ohms.

I'd think it'd be evently distributed, 15ohms a side.

But it's worth 3 marks!

I doubt you'd get 3 marks from an exam question for simply saying "30 ohms".

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

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.

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

I think the answer is EIGHTY EIGHT MILES PER HOUR!

The gayby forum posted that before i was finished typing

29.5 ohms.

It loses 0.5 due to heat pressure and sasquatching.
