1. Well, we want to find the relationship between resistance and temperature. We asked the lab techie and he said to use some Nichrome wire in a coil and test the potential difference, current and temperature of the wire.

We're having a problem getting it set up. We're not sure how to set up the circuit.




2. N.A.



3. We've tried having a power pack that goes into the wire then back into the power pack, and the wire gets hot. Are we doing this right? Could someone please help us out with a circuit diagram or something?


Thanks a lot guys.
1. The problem statement, all variables and given/known data



2. Relevant equations



3. The attempt at a solution

Connect the ammeter in series and the voltmeter in parallel. Not too sure how you plan to measure temperature though. Unless you have a resistor that is affected by temperature.

Relationship between temperature and resistance


I think this pdf might help you: http://www.owlnet.rice.edu/~phys102/Lab/expt03.pdf

It is the lab manual for a resistivity experiment for PHYS 102.

Cheers.

Maybe you could use a thermistor as a temperature sensor.
