NTC PTC | Positive Temperature Coefficient | How To Test PTC Thermistor

Hello friends in today's video we will experiment with PTC.
And will also see how they work and why they are used in circuits.
They are also called temperature-sensors or thermal resistors.
PTC thermistors are temperature-dependent resistors based on very special semiconductor ceramics with a high positive temperature coefficient. They exhibit relatively low resistance values at normal room temperature. When a current flows through a PTC the heat generated raises the temperature of the PTC. Once a certain temperature is exceeded, the resistance of a PTC rises significantly.
It also called degaussing the crt tv.
