Relationship between temperature and resistance

Sir Pwn4lot

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.

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.

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.

Maybe you could use a thermistor as a temperature sensor.
