Prediction for determining resistivity experiment?

By John | Published: December 25, 2011
Prediction for determining resistivity experiment? I am looking for a good hypothesis/prediction for my ”determining resistivity” experiment lab report. we are supposed to get it from internet but I couldn’t find. It would be better if it contained ‘if’ and ‘then’ . thank you in advance. for example ( if the length increases then resistivity increases ) best answer/10pts [...]
