- 26-4 Resistance and Resistivity,Calculating Resistance from Resistivity
- : resistivity
- o: resistivity at selected reference point
- T: temperature
- To: reference temperature
- : temperature coefficient resistivity
- The relation between Temperature and Resistivity for copper (for metals in general) is fairly linear over a rather broad temperature range.
