... As the temperature rises, the resistance of the thermistor falls. (TURD) So the voltage across the thermistor falls. This means the voltage across the variable resistor goes up (as the two resistors share the supply voltage). When the voltage across the variable resistor rises above 0.7 V, the NPN t ...
