• In thermistor room temperature is-4%to-5% but in sensistor temperature range is 22^c to 450^c
• temperature range is 💯 degree Celsius to 350 degrees Celsius but in sensistor temperature co efficient of resistance is 0.7 degrees Celsius
• resistance range from few ohms to megha ohms but in sensistor resistance range from 0.5 ohms to 100 megha ohms

What is the difference between thermostat and thermistor?
one is called a thermostat and the other is called a thermistor - Ross Henderson
How is a thermistor used in a baby incubator?
A thermistor changes its resistance when the temperature changes. This means as the room temperature changes the current in the circuit containing the thermistor changes. This change in current is detected by the heater circuit, turning the heater on and off.
Why is a thermistor used in a fridge?

How could you change the resistance of the thermistor?
Change its temperature.
What is the difference between thermostat and thermister?
Thermostat is a mechanical device that reacts to heat. As heat is applied the thermostat contracts and allows water to flow through the system. A thermistor is a thermal resistance sensor that also reacts to heat. There are two kinds, one is a negative coefficient and is a positive coefficient. As heat increases it changes the resistance value of the thermistor. That resistance value is transmitted to the computer and/or temperature gauge. Through computation the computer can can tell what temperature the engine is at to make decisions on how it should be run.

What is the function of a sensistor?
the sensistor functions as a temperature sensitive resistor with a positive coefficient of temperature.used for temperature compensation in various circuits
What is the relationship between current and voltage in a thermistor?
V=IRR changes as a result of the change in temperature.
What kind of thermometer has a thermistor at its end?
A RV absorption refrigerator uses a thermistor as a thermostat. The thermistor is moved up or down to regulate the refrigerator temperature.
Why is a thermistor a non ohmic conductor?
Ohm's law states that the current and potential difference (voltage) are directly proportional, provided the temperature is constant. The resistance of a thermistor is dependant on the temperature, so it does not obey Ohm's law. Components that do not obey Ohm's law are non-ohmic conductors.
What is thermoresistive?
A thermistor is thermoresistive.
Is a oxygen sensor a thermistor sensor?
No
What is the configuration of cascade amplifier?
In a cascade amplifier, two identical or non identical amplifiers are cascaded ,i.e., connected in series through a capacitor. They are mostly common emitter amplifiers that are cascaded together.The final gain of the cascaded amplifier is the product of the first amplifier's gain and the second amplifier's gain. However, the bandwidth of the cascaded version becomes lesser than the individual gains.
Is potentiometer and Thermistor are variable resistors. How please explain?
A: A potentiometer is a manual device to change the resistance A thermistor changes as a function of environment temperature
How do you tell if a faulty thermistor?
While some people use a much more exhaustive and precise testing procedure, a very simple test can uncover the most common problems with a thermistor: * measure the resistance of the thermistor at room temperature with an ohmmeter. If this resistance is 0 (short) or infinity (open), then something is connected incorrectly or the thermistor has been destroyed. (These are the most common problems). If that test looks good, then a followup test can uncover nearly all the remaining possible problems with a thermistor: * put icewater in a ziplock bag and press it against the thermistor. Then measure the resistance of the themistor at freezing. The two measured values of resistance are usually adequate to identify what kind of thermistor it is. If both values are practically the same, then it's not really a thermistor -- perhaps someone has accidentally substituted a resistor. If one or both values are not the expected values, perhaps someone has accidentally substituted a different kind of thermistor.
