The circuit shown in Figure DP 3-11 is designed to
help orange growers protect their crops against frost by sounding
an alarm when the temperature falls below freezing. It contains a
thermistor that has a resistance Ro=620 N at the temperature
To=20 °C=293 °K and ß= 3330 °K. (See problem DP 3-9.)
The alarm will sound when the voltage at the - input of
the comparator is less than the voltage at the + input. Using
voltage division twice, we see that the alarm sounds whenever
