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.
