Instrumentation Amplifier using Transducer bridge(Derivation and Working)in English

[@dipaligudekar2285]

Thanks for the information mam, even if the unity gain amplifier are wrongs your explanation is absolutely easy to understand.

[@ujjawalkumardubey3186]

Awesome explanation mam Thanks a lot

[@RehuRehu-oy3jd]

i think that unity feedback should have negative feedbacks?? and also Vab=Va-Vb(by standard books)

[@creativeeee]

excellent video very informative and helpful

Glad you liked it

[@cikgutaiff]

Why is A1 and A2 connected as positive feedback?

[@LearningElectronics]

non inverting configuration should be used its mistake of drawing figure

[@sindhujagalam3007]

Vab=va-vb or vb-va

[@cikgutaiff]

@@sindhujagalam3007 By definition must be: Vab = Va-Vb

[@priyabrata_roy]

you are right , A1 A2 are voltage follower, so their inverting terminal should get shorted with output terminal and we give input signal to non-inverting terminal... however those two buffer diagram plus minus sign should get altered , then it's ok

[@helloworld9057]

what if i place ldr at place of thermister ???

[@mmh1922]

Buffer stage input terminals must be swapped.

Very nice mam

In the circuit of Figure 1, R1 = 1 kΩ, RF =4.7 kΩ, RA=RB=RC=100 kΩ, Vdc = +5 V, and op-amp supply voltages =  15V. The transducer is a thermistor with the following specifications: RT= 100 kΩ at a reference temperature of 25⁰C, temperature coefficient of resistance = -1 kΩ/⁰C. Determine the output voltage at 0⁰C and at 100⁰C. MAM PLZ SOLVE THIS FOR ME IT IS VERY IMP FOR ME

[@hwrsh]

do you have the solution?

[@luizbiazoto5327]

schematic is wrong. Positive feedback will result in amplifier overflow...
