When the temperature of a thermistor increases, the current flow through it increases due to the characteristics of the thermistor. A thermistor is a type of resistor that changes its resistance with temperature fluctuations. There are two main types of thermistors: NTC (negative temperature coefficient) and PTC (positive temperature coefficient).

In the case of an NTC thermistor, which is the most common type used in temperature sensing applications, the resistance decreases as the temperature rises. This lower resistance allows more current to flow through the thermistor. Therefore, with an increase in temperature, the current flow through the thermistor increases.

Understanding this behavior is crucial for applications that utilize thermistors for temperature measurement and control. The relationship between temperature and resistance is fundamental to how these devices operate within various electronic circuits.
