Thermistor Basics - NTC PTC

The video tutorial explains thermistors, which are resistors that change resistance with temperature. It covers two types: Positive Temperature Coefficient (PTC) and Negative Temperature Coefficient (NTC). PTC thermistors increase resistance with temperature, while NTC thermistors decrease resistance. The video also delves into atomic structure, explaining how electrons in different shells affect conductivity. It highlights the behavior of semiconductors, which can act as insulators or conductors based on temperature, due to the proximity of the conduction band to the valence shell.
