Notes:
- Conversion factors are base on Temp. Coefficient of Resistance of copper (α20)=0.00393
- For any other temperatures out side the table range
R20=RT/1 + α20(T-20)
R=R20{1 + α20(T-20)}
Where
R20 = Reference resistance at 20 deg C
R T = Resistance at T deg C
T = Temperature at which measurement is made or to which reference Res. is required to be converted.
α 20 = Temperature Coefficient of resistance of copper conductor.
