The component used in electric circuits that is sensitive to temperature is a thermistor. Thermistors are temperature-sensitive resistors whose resistance changes significantly with temperature fluctuations. There are two main types:
- NTC (Negative Temperature Coefficient) thermistors, where resistance decreases as temperature increases, commonly used in temperature sensors and control systems.
- PTC (Positive Temperature Coefficient) thermistors, where resistance increases as temperature rises, often used in resettable fuses or heating elements.
Thermistors have widespread applications, including temperature sensing in fire alarms and temperature regulation in various electronic devices.
