Measuring Temperature Of Electrical Wire

  1. Oct 23, 2007 #1
    Hello,

    I'm currently doing a College Physics Project for expotential decay / growth. I have an idea of the experiement I want to perform but I need to find a way of measuring the temperature of wire as I put a voltage through it. Is there a formula which may be useful or any techniques people have come across?

    Thanks for the Help,

    Stefan

    P.S Please move if it is in the incorrect category.

    Hmmm...How about an infrared thermometer?

    Or a thermocouple and a drop of superglue ( cheaper but slower to react).

    Don't forget that you need to have your measuring devices calibrated. If you are purchasing a hand-held meter, you should ask for a certificate of calibration with data. There might be some "nonlinearity" that can be used for correcting the reading. Thermocouples meters really should be calibrated with their thermocouple attached.

    Regards
