NTC v/s PTC Difference And Applications

NTC and PTC are known as thermistors, which can be further known as temperature-controlled resistance. Now something is related to resistance but how it works and which type of circuits can be designed using these components. Let’s know the working concept and then we will use them practically. The value of these thermistors is not…
