Chapter 3, Problem 58P

1. Find the resistance of the thermistor having the characteristics of Fig. 3.36 at $-50°\text{C,}\text{50°C,}$
2. and $200°\text{C}\text{.}$
3. Note that it is a log scale. If necessary, consult a reference with an expanded log scale.
4. Does the thermistor have a positive or a negative temperature coefficient?
5. Is the coefficient a fixed value for the range $-100°\text{C}$
6. to $400°\text{C?}$
7. Why?
8. What is the approximate rate of change of p with temperature at $100°\text{C?}$
