Advanced Project -- Wheatstone Bridge for TCR measurements
Ok, so I have to do this experiment on my own as part of my coursework this year and I picked something called the temperature coefficient of resistance.
I think I basically have to determine the TCR or copper and I'm almost certain that I need to use a Wheatstone bridge. The theory behind the experiment makes sense to me I guess, but I'm not very good at the practical stuff and I'm not really sure what apparatus I need for it. I have to prove the formula:-Rt = Ro (1 + alpha(t) ) if that helps at all.
Unfortunately, the only book my school has with any information about my experiment isn't in the library at the moment and I'm really struggling to find a version online that uses a Wheatstone bridge.
If anyone has done this experiment before or has any ideas on how I might set it up, I could really use the help :/
