The resistance R is influenced by the temperature as follows:

This produces a resistor of resistance 30 kilohms at the nominal temperature tnom. If the temperature T7 v e8 J, Q5 I
is different from tnom, the resistance is 30,000*(1+0.01*(T-tnom)+0.0001*(T-tnom)*(T-tnom)). For- i+ I1 b: o( y$ m! n& [
