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.
What is the difference between the sensistor and thermistor?
Thermistor: Negative temperature coefficient Sensistor: Positive temperature coefficient.
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 difference between thermostat and thermistor?
one is called a thermostat and the other is called a thermistor - Ross Henderson
What is the opposite of resistance?
The opposite of resistance (opposition) could be cooperation, or acquiescence, or surrender. The opposite of resistance (electrical) could be conductance.
Why does the resistance of a thermistor change when you change its temperature?
The resistance of a thermistor changes when its temperature changes due to the inherent properties of the thermistor material. In a negative temperature coefficient (NTC) thermistor, the resistance decreases as the temperature increases, whereas in a positive temperature coefficient (PTC) thermistor, the resistance increases as the temperature rises. This change in resistance is caused by the variation in the number of charge carriers (electrons or holes) and their mobility within the material as temperature changes.
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

Is the resistance of a thermistor measured in degrees celsius?
resistance is measured in 'ohms'. A thermistor basically tells u how temperature affects resistance in a circuit, generally the higher the temperature (degrees) the less resistance
Is a NTC thermistor different from PTC thermistor?
Yes, NTC stands for Negative temperature coefficient. This means the resistance goes down as temperature goes up. A PTC has a positive temperature change. As temp goes up, the resistance will increase also.
What are the electrical characteristics of a thermistor?
Varies its resistance with regard to temperature.
Does the resistance go higher or lower when a thermistor gets hot?
the therminster will get hotter when the resistance is lowed
What does a Thermistor do in a circuit?
A thermistor is a type of resistor specifically designed to have a predictable change in resistance depending on the temperature surrounding it. All resistors and, in fact the resistance of all components are succeptable to changes in temperature. The thermistor however, is specifically designed to exploit this in order to be able to measure temperature. They are commonly found in all sorts of temperature sensing circuits, from your digital thermostat in your house to your digital meat thermometer.
How could a thermistor be used to determine airflow in cubic feet per minute - a thermistor measures temperature changes - how do you change that to cubic feet per minute?
You must have your foudation cubic feet per min first. Then using the thermistor measure the temperature and it should hold steady. The fluctuations in the resistance will show degradations in the airflow. More ohms the less airflow. So Temp % resistance = x Airflow =r known computed airflow =f ix= diff r/f okay. i think i understand.
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.
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.
How does a thermistor work?
A thermister is a resistor that depends on tempature, the higher the temp the lower the resistance t, the lower the temp the higher the resistance
