WebWikipedia WebNjë thermistor është një lloj rezistori, rezistencë e te cilit ndryshon me temperaturën. Fjala është një portmanto e fjalëve termike dhe rezistencë . Thermistorët janë përdorur gjerësisht si limitues korrenti , sensorë temperature, qarqe vetë-mbrojtës nga korrenti i tepërt, dhe elemente për ngrohje vetë-rregulluese.

WebThe equation is: 1 T = A + B ln ( R) + C ( ln ( R)) 3. where: T is the temperature (in kelvins) R is the resistance at T (in ohms) A, B, and C are the Steinhart–Hart coefficients which vary depending on the type and model of thermistor and the temperature range of interest. (The most general form of the applied equation contains a ( ln. A thermistor is a semiconductor type of resistor whose resistance is strongly dependent on temperature, more so than in standard resistors. The word thermistor is a portmanteau of thermal and resistor. Thermistors are divided based on their conduction model. Negative Temperature Coefficient (NTC) … See more Depending on materials used, thermistors are classified into two types: • With NTC thermistors, resistance decreases as temperature rises; usually due to an increase in conduction electrons bumped up by … See more In practical devices, the linear approximation model (above) is accurate only over a limited temperature range. Over wider temperature ranges, a more complex … See more When a current flows through a thermistor, it generates heat, which raises the temperature of the thermistor above that of its environment. If the thermistor is being used to … See more The first NTC thermistor was discovered in 1833 by Michael Faraday, who reported on the semiconducting behavior of silver sulfide. Faraday noticed that the resistance of silver sulfide decreased dramatically as temperature increased. (This was also the … See more Thermistors are typically built by using metal oxides. NTC thermistors are manufactured from oxides of the iron group of metals: e.g. chromium ( See more NTC (negative temperature coefficient) Many NTC thermistors are made from a pressed disc, rod, plate, bead or cast chip of See more PTC • As current-limiting devices for circuit protection, as replacements for fuses. Current through the device causes a small amount of resistive heating. If the current is large enough to generate more heat than the device can … See more plants chickens hate
