WebNov 25, 2024 · How Does a Thermistor Work? 1. NTC or PTC A thermistor’s most basic feature may be whether its resistance goes up or down with increasing temperature. Those that lose resistance have a negative temperature coefficient (NTC), while those that gain resistance have a positive temperature coefficient (PTC). WebJan 15, 2014 · A thermistor is a component that has a resistance that changes with temperature. There are two types of thermistor, those with a resistance that increase with temperature (Positive Temperature Coefficient – PTC) and those with a resistance that falls with temperature (Negative Temperature Coefficient – NTC). Temperature coefficient:

http://www.gcsescience.com/pe28.htm WebANSWER: A. The resistance of the thermistor increases as the temperature decreases. Since the thermistor and resistor R are connected in series, the current I in both of them is the same. Ohm’s law states that V = IR. Since the resistance of the thermistor increases, and I is the same, the potential difference V across it increases.
