How to Build Simple Thermistor Circuits

How to Build Simple Thermistor Circuits. In this article, we go over how to build simple thermistor circuits. A thermistor is a specialized resistor which changes resistance value depending on the amount of heat which it is exposed to. Its main characteristic is that it is thermally sensitive; in response to the heat it is exposed to, it alters its electrical resistances to changes in temperature.

Introduction to Basic Electronics, Electronic Components ...

An electronic circuit is a circular path of conductors by which electric current can flow. A closed circuit is like a circle because it starts and ends at the same point forming a complete loop. Furthermore, a closed circuit allows electricity to flow from the (+) power to the (-) ground uninterrupted.
