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.

Hahaha
Hush your mouth, grebil fase.
I believe it's 600 joules.
GET OUT
Hmm... I'd say 15 Ohms- as resistance depends on length of wire, cross-sectional area (not relevant as it's uniform) and temperature- which isn't stated.
A guess, though.
A guess, though.
Wont it remain 30 Ohms? Its still travelling through the same amount of distance, I’m sure bending it wont effect it that much.
It's 3 marks though, it won't be that simple dear pooface/

Ta.
A diagram would have helped because in not sure if it’s going through the whole wire or just half it.
