Help,
I've just been given this course work on resistance of wore and I donw understand it. Can anyone help?
All I know is r=v/i
and that it's all Ohms law and thats it.
Help.
PLease can some one e-mail me with some answers.
Thanks you in advance

Hey Im not great a phy but hmm hope this might help- and you might also want to check in a text book to see if Im right *btw you could search on google or something they sometimes give sample c/work essays they use to help me alot*

resistance= voltage/ current.

So this means the if you draw a graph of voltage against current, the slope of the graph would give you resistance. It should be a straight line graph coming down from right to left, as the current through a resistor at a contstant temp is directly proportional to the voltage, so if one goes up the other should go up at the same rate.

You might also want to look into factors affecting the resistance of the wire eg temp.

Anyways hope this helps

have you decided to do thickness of wire? or length of wire? or material of wire? or something

you just need to investigate the factors which affect the resistance of wire
