- This electronics video tutorial provides a basic introduction into thermistors also known as temperature dependent resistors. There are two types of thermal resistors - NTC and PTC. PTC thermistors are used as resettable fuses while NTC thermistors are typically used as temperature sensors.

Dude how much knowledge have you got over these years , hats off for you sir
Relax just be more tea ✅✌️
Good video!
Would like to point out that at 7:50 the formula should be:
R1 = R2 exp.^beta ((1/T1) - (1/T2))
It was done correctly with the example question later in the video though. Just saying for those watching that they should watch through the whole video and not stop at 7:50.
Good job!
Thanks a lot for making this video, this gave me a fundamental understanding to develop further, this is helping me in my internship, where i'm currently working on a ntc thermistor to record the temprature of a battery while it heats during charging or discharging. 😁
hey man. may go bless. u may attain nirwana for the service you do to this society and educating idiots like us
Wespuchchi Nasarawo ✅✌️
Lecture was great ...!
And keep it up
he done it again, every time i go further in phys, math, chem tertiary content, i'll find a OCT vid at some point loll
So cool, I heard about thermistors a long time ago though I forgot what they could do. nice video!
Your video helped me a lot thanks
much needed. good one
This was very useful and clear. Thanks a bunch!
Please make video on cemos and mosfets. Transistor series would be much appreciated brother
thank you very good explanation thumbs up a sub!!!
07:56 That must be ln(R2/R1) not ln(R1/R2).. (if i am not blind..)
Mr.
thank you so much for your help
Thank you so much that you made me succeed
Thank you from all of my heart
Without you i couldn't be an educator
Ammar Saber ✌️
THANKS ALOT
This guy knows everythings in the universe..
Well, that was easy
thank you
Thank you man for the explanation, how about ptc ?
That beta equation is just for NTC or also for PTC termistors? When i calculate with it on a PTC, my beta equals a negative valor.
O thanks, very knowledge video. Otangizga balli.
Hi, I've got a NTC 5D-11 on a power supply board, it was cracked so I bought 2pcs just to have a spare. I tested the new parts and I am getting continuity, is it supposed to have continuity? both parts have it.
Thanks!
Good
Are you a god? Do you know everything? Do you will things into existence, only with the power of your mind? You seem to have a detailed video on every science, engineering, and math-based subject.
I have an window A/C unit that I need to get the room to 60 degrees but the unit will only allow me to set it to 64. I am trying to control the temp by using and Inkbird temperature controller that turns the A/C unit off and on via the outlet based on the inkbird's sensor. In and effort to get this to work, I have tried relocation the A/C unit's thermistor and insolate it but the results are inconsistent.
Can you tell me if I can provide a set temperature reading on the sensor circuit be removing the thermistor and replacing it with a 9K ohm resistor so that it reads a constant 30C?
Requesting a PTC calculation video
Calculation: Supposing (1/T1 - 1/T2) as X
R2= R1e^(BX)
R2/R1 = e^BX
ln(R2/R1) = lne^BX lne=1, shifting the power of e to the base
ln(R2/R1) = (1) BX
(ln(R2/R1) )/ X = B replacing the value of X
B= (ln(R2/R1)) / (1/T1-1/T2)
I agree with your math. I’m very confused why he has ln(R1/R2)…?
Love it much ❤ from pak🇵🇰
Wow!
OMA Nice ❤️
I have a circuit board that has either a ntc 3d-9 or a 8d-9. I cant tell cuz it exploded. Is it a big deal if i get it wrong? I cant find a parts list for the circuit board. Thanks
Is a variable resistor with a bimetallic strip a "thermistor?"
I find using a power equation of the type Tk = aR^b works very well over a wide temperature range, certainly good enough to 0.1C. Each thermistor has to be calibrated separately with its own a and b coefficients.
Thats nice, why dont you make your own videos?
@@ME2DAY Too much work!
Eeee boyy!
saya lagi mencari NTC dengan amper sekitar 15 - 30 A, Hambatan sekitar 30 - 100 Ohm. saya sudah search di google masih belum nemu juga. minta sarannya pakai tipe apa ya?
Great video: however, when solving the log equation, I’m getting beta as [ln(R2/R1)]\[(1/T1)-(1/T2)]. What you have is correct however if R1 = R2 * e^(beta((1/T1)-(1/T2))).
Hey Reed Richards.
Ive got equipment with 64 NTC thermistors imbedded inside.
I need to monitor each one on a regular basis, and set a high alarm.
I have a stc1000 temp controller and was wondering if something Arduino based could switch between them all over say a two or three minute period, giving me constant monitoring✅
Have you tried to use remote temperature sensors instead? Like the TMP468
@@bp8864 I need to use the ones already embedded in the battery modules☹️
@Roger Crier
Ive got the same plan like you. I try to read out the temperature values out of 845 thermistors separately.
In the future I want to build out a powerwall with 3380 lithium cells, of course with full temperature monitoring based on arduino nano.
In your case, the job can do the set of 74HC595 chips (eight in series of them) and one arduino probably.
If you know, how for example the 8x8x8 led cube works with the same setup, this is easy to do.
You can switch between the sensors one by one, read out the data, then switch on the next one....
@@rolandroka2082
I will pass that info to my friend, who knows more about it!!✅
Thanks
Hmm well I had that wrong I was certain I’d seen NTCs used as inrush resistors etc unless they just used the wrong part lol ?
Anyhow good to actually learn what the N And P stand for.
Stay positive man
Low voltage= high current
Hi Ricardo, I have a research on the topic of thermostat. I need thermistor equation as well as the linear relationship. Can I contact you via Facebook
I think T_1 and T_2 in equation R_2 should be flipped
Hi - At 13:30 yous say Natural Law ? why write Ln ? you did not explain.
Natural log is ln, while log is ln base 10
