Termisanasto

Termisanasto, also known as thermistor, is a type of resistor whose resistance varies significantly with temperature. This property makes thermistors useful in various applications where temperature measurement or control is required. Thermistors are typically made from semiconducting materials, such as oxides of metals like manganese, nickel, cobalt, iron, or copper.

There are two main types of thermistors: negative temperature coefficient (NTC) and positive temperature coefficient (PTC). NTC thermistors have a resistance that decreases as temperature increases, while PTC thermistors have a resistance that increases with temperature. The resistance-temperature relationship of a thermistor is highly non-linear, making them suitable for precise temperature measurement and control.

Thermistors are widely used in temperature sensing and control applications, including thermostats, temperature compensation in electronic circuits, and temperature measurement in various industries. They are also used in self-regulating heating elements, such as those found in electric blankets and toasters, where the resistance of the thermistor increases with temperature, limiting the current and preventing overheating.

In summary, termisanasto, or thermistor, is a temperature-sensitive resistor used in various applications for temperature measurement and control. Its resistance varies significantly with temperature, making it a valuable component in many electronic devices.
