a. Referring to Fig. 16.41, determine the current at which a 25°C sample of the material changes from a positive to a negative temperature coefficient. (Figure 16.41 is a log scale.)

b. Determine the power and resistance levels of the device (Fig. 16.41) at the peak of the 0°C curve.

c. At a temperature of 25°C, determine the power rating if the resistance level is 1 MΩ
