All about thermistors for measuring and controlling temperature, including how to use the thermistor that's in an automobile coolant temperature sensor. I talk about the difference between Positive Temperature Coefficient (PTC) thermistors and Negative Temperature Coefficient (NTC) thermistors. I talk briefly about my experiment to test if cold water boils faster than hot water and then talk about the effect of the thermistor's • changing resistance on the electrical current running through a PC fan, to turn the fan on and off. I go over the electrical circuit for it in detail, incuding the homemade power supply, thermistor, PC fan and wiring. • This video has correct English captions.
