Temperature-Resistance Relationship
In a 10k type 3 thermistor, the relationship between temperature and resistance is highly nonlinear. As the temperature rises, the resistance of the thermistor decreases. This is because the thermistor's material is a semiconductor, and the increased thermal energy causes the electrons to become more mobile, reducing the resistance.
The thermistor's resistance curve can be divided into three regions: the high-temperature region, the mid-temperature region, and the low-temperature region. In the high-temperature region, the resistance decreases rapidly with increasing temperature. In the mid-temperature region, the resistance decreases more slowly with increasing temperature. In the low-temperature region, the resistance decreases very slowly with increasing temperature.
Thermistor Resistance Curve Characteristics
- The resistance curve is nonlinear, with a negative slope.
- The resistance decreases rapidly with increasing temperature in the high-temperature region.
- The resistance decreases more slowly with increasing temperature in the mid-temperature region.
- The resistance decreases very slowly with increasing temperature in the low-temperature region.
- The resistance curve can be approximated by a logarithmic function.
