Relationship between temperature and resistance

  1. Aug 31, 2009 #1
    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.

    Maybe you could use a thermistor as a temperature sensor.
