A platinum resistance thermometer has a resistance 4\(\Omega\) at 0oC and 10\(\Omega\) at 100oC. Assuming the resistance changes uniformly with temperature. Calculate the resistance of the thermometer when the temperature is 45oC.
\(\frac{R - 4}{10 - 4} = \frac{45 - 0}{100 - 0}\)
R = \(\frac{670}{100} = 6.7\Omega\)
