Discussion Overview

The discussion revolves around the resistivity of NiCu alloy, specifically whether it is 3.5*10^8 Ω*m or 35*10^8 Ω*m. Participants are exploring the correct value and its implications for experimental results.

Discussion Character

  • Exploratory, Technical explanation, Debate/contested

Main Points Raised

  • One participant expresses confusion over the resistivity value of NiCu alloy, noting a discrepancy between lab data and theoretical calculations.
  • Another participant suggests that the resistivity value may depend on the composition of the alloy and references external sources for clarification.
  • A third participant points out a potential misunderstanding regarding the notation, indicating that the correct interpretation may involve a negative exponent.
  • A later reply confirms the correction regarding the exponent, acknowledging the mistake in notation.

Areas of Agreement / Disagreement

Participants do not reach a consensus on the correct resistivity value, and there are competing interpretations regarding the notation and its implications.

Contextual Notes

The discussion highlights the importance of precise notation in scientific measurements and the potential for confusion when dealing with different representations of resistivity values.

I am very sorry because this post seems spammy, but I cannot, for the life of me, find the resistivity of NiCu alloy.
My lab has it as 35*10^8 Ω*m, and when i compare my calculated value of resistance to the theoretical it is off by a factor of 10. This causes me to think that there is a typo and it should be 3.5*10^8…
Could someone please confirm this?
I cannot find it by googling (and I've been trying for the past hour or so).

Both of you actually mean 35 * 10-8 Ωm (note the sign), don't you?
 
Yes, you are right. At least I meant negative 8.:)
