Chapter 18, Problem 24ICA

The resistance of a typical carbon film resistor will decrease by about 0.05% of its stated value for each degree Celsius increase in temperature. Silicon is very sensitive to temperature, decreasing its resistance by about 7% for each degree Celsius increase in temperature. This can be a serious problem in modern electronics and computers since silicon is the primary material from which many electronic devices are fabricated.

Create a proper plot to compare a carbon film resistor with a resistor fabricated from specially doped silicon (“doped” means impurities such as phosphorus or boron have been added to the silicon).

For relatively small temperature differences from the reference temperature, this process is essentially linear. Use polyfit to determine linear models for each data set. For each model, add the trendline and the associated trendline equation to the graph. Use an appropriate location for the equations to clearly associate them with the correct trendline.
