For the thermistor of Fig. 16.40, determine the dynamic rate of change in specific resistance with temperature at T = 20°C. How does this compare to the value determined at T = 300°C? From the results, determine whether the greatest change in resistance per unit change in temperature occurs at lower or higher levels of temperature. Note the vertical log scale.
