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.
What does a thermister do in a circuit?
A Thermistor Is essentially a variable resistor. The resistance of the thermistor changes with temperature. They're often used to regulate heating elements - like those found in cookers.
What is advantages of thermistor?
A thermistor an electrical resistor that resistance changes with temperature. There are two advantages of a thermistors one is it been more sensitive that the RTDÕs and thermocouples and two is has a quick response time.
When does a thermostor obey ohm's law?
I hope you mean the thermistor. If so,well it does not obey Ohms law. When current flows through the thermistor its temperature start increasing which reduces the resistance of the thermistor. A reduction in resistance at the same supply voltage will cause the current to increase. Thus it's not obeying Ohms law.
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.
What is the difference between thermostat and thermistor?
one is called a thermostat and the other is called a thermistor - Ross Henderson
What is thermoresistive?
A thermistor is thermoresistive.
Is a oxygen sensor a thermistor sensor?
No

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.
How could you change the resistance of the thermistor?
Change its temperature.
Why is a thermistor used in a fridge?
