I am currently studying a coursewok set on sensors. If anyone knows the method and circuit for an NTC thermistor experiment or any information on the thermistors at all it would be greatly appriciated.

Hey thank you very much for that! Does anyone know much about potential divider circuits for thermistors? I can't seem to get my head around it. Any useful equations I should look out for? Thanks very much everyone!

Hey Noj,
There have been a few posts recently on Physics Forums in regards to https://www.physicsforums.com/search.php?searchid=130798 [Broken]
and https://www.physicsforums.com/search.php?searchid=130799 [Broken]
some of the posts are the same, but it's really worth having a look, see if you can get any ideas.

Also, if you look at the links at the top of this page, they're ads, but worth having a look at too

Hope the result-taking is going well
:biggrin:

1. What is an NTC thermistor?

An NTC thermistor is a type of temperature sensor made from a material called a negative temperature coefficient (NTC) material. This material has the property of decreasing its electrical resistance as temperature increases.

2. How does an NTC thermistor work?

An NTC thermistor works by measuring changes in electrical resistance as temperature changes. As the temperature increases, the NTC material's resistance decreases, allowing more current to flow through the circuit. This change in resistance can be used to calculate the temperature of the thermistor.

3. What is the purpose of this experiment?

The purpose of this experiment is to demonstrate the use of an NTC thermistor as a temperature sensor and to observe the relationship between temperature and electrical resistance in the thermistor. This experiment can also be used to calculate the temperature coefficient of the NTC material.

4. What materials are needed for this experiment?

To conduct this experiment, you will need an NTC thermistor, a power supply, a voltmeter, a resistor, a multimeter, and wires for connecting the circuit. You may also need a heat source, such as a hot plate or a hairdryer, to change the temperature of the thermistor.

5. What are the potential applications of an NTC thermistor?

NTC thermistors have a wide range of applications, including temperature sensing and control in electronic devices, automotive systems, and household appliances. They can also be used for temperature compensation in circuits and as part of self-regulating heating systems.
