4Question 4.
True or False: Thermal sensors have a fast response time.
- True
- False
Show hintHide hint
Think about the characteristics of thermal sensors.
Question 5.
A MEMS thermal sensor measures the resistance of a thermistor at varying temperatures. At 25°C, the resistance is 10 kΩ, and at 75°C, the resistance drops to 2 kΩ. Calculate the temperature coefficient of resistance.
