Theoretical Resistance Values
The relationship between resistance and temperature can also be calculated
using the following equations:
Where A, B, C, D, A
1,
B
1,
C
1,
and D
1
are constant values that depend on the
material; see table below for values. R
ref
is the resistance value at a reference
temperature, which is room temperature in this case. T is the temperature in K.
