THERMISTOR Meaning and
Definition
-
A thermistor is a type of resistor whose electrical resistance changes with variations in temperature. It is a temperature-sensitive electrical component commonly used in electronic circuits for accurate temperature measurement and control.
In terms of structure, a thermistor consists of a ceramic or semiconductor material with a high degree of temperature sensitivity. The material is typically made of metal oxides, such as manganese, nickel, or cobalt. These metal oxide particles are mixed with a binder material and then compressed into a desired shape, often resulting in a small bead or disc.
One characteristic of a thermistor is its negative temperature coefficient (NTC) or positive temperature coefficient (PTC). NTC thermistors have a resistance that decreases as the temperature increases, while PTC thermistors exhibit the opposite behavior, with resistance increasing as temperature rises.
Due to their thermal response characteristics, thermistors are widely used in various applications, such as temperature sensors, thermostats, and thermal compensation devices. They provide accurate temperature readings in a compact size and are relatively inexpensive compared to other temperature sensing devices.
In summary, a thermistor is an electrical component whose resistance is influenced by temperature changes. It is frequently employed in electronic systems for temperature measurement and control, offering a reliable and cost-effective solution.
Common Misspellings for THERMISTOR
Etymology of THERMISTOR
The word "thermistor" is a combination of two words: "thermo" and "resistor".
1. "Thermo" derives from the Greek word "thermos", meaning "hot" or "heat".
2. "Resistor" refers to an electronic component that resists the flow of electric current.
So, a "thermistor" is a resistor that changes its resistance with temperature. The term was first coined in the 1920s, combining "thermo" with "resistor" to describe this specific type of temperature-sensitive resistor.
