Measuring Temperature Of Electrical Wire

Click For Summary

Discussion Overview

The discussion revolves around methods for measuring the temperature of electrical wire while applying voltage, as part of a college physics project focused on exponential decay and growth. Participants explore various techniques and tools for accurate temperature measurement in this context.

Discussion Character

  • Exploratory, Technical explanation, Debate/contested

Main Points Raised

  • Stefan inquires about formulas or techniques for measuring wire temperature during an experiment involving voltage.
  • One participant suggests using an infrared thermometer as a potential solution.
  • Another participant proposes using a thermocouple with superglue, noting it may be a cheaper but slower option.
  • A further contribution emphasizes the importance of calibrating measuring devices, mentioning that calibration certificates should be requested for hand-held meters and that thermocouples should be calibrated with their specific thermocouple attached.
  • There is a mention of possible nonlinearity in readings that could require correction.

Areas of Agreement / Disagreement

Participants present multiple methods for measuring temperature, but there is no consensus on the best approach or the necessity of calibration, indicating a range of opinions and techniques without resolution.

Contextual Notes

Limitations include the potential nonlinearity of measurements and the need for calibration, which may depend on specific devices used. The discussion does not resolve these issues.

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
