Adam with UConn HKN presents a simple ideal Operational amplifier (OP-amp) example problem. Adam explains the most important principles of the OP-amp and then goes to solve for the output voltage and all other circuit parameters. The methods taught in this video can be used on any op-amp problem.

Howdy All! Some corrections for you! Vo = -3V is correct, however when we calculated i_3, we forgot our negative sign! i_3 = -0.12mA is the correct answer, meaning that our answer for io is: io = i_2-i_3 = 0.075mA - (-0.12mA) = 0.195mA (into the OpAmp) Sorry for the sign error! ~Andrew

Some are still incorrect

bro u realized after 6 years mannnnn

@bakugan366 6 лет назад

There is a mistake at the end of your calculations. You forgot the negative sign on i3 which would have made i2 positive meaning that there was current entering the op amp from the output side. Please add an annotation or add it to the description to clarify.

@joanitarzzalwango6392 Год назад

i3 doesn't have a negative

loudest intro i have ever heard

@kimedwardoclida2137 6 лет назад

Io is wrong since Vo =-3v if you KCL on that node it must be 75uA=Io+((-3-0)/25K) = Io-120uA then Io = 195uA

Plz suggest me a book for critical problem on op amp

Very helpful thank you

@christinaminnigh5748 6 лет назад

Would you be able to help me solve a problem?

@mfanelovehealthfitness4204 4 года назад

The formula that you used to calculate the output voltage(Vout) which is 0v+3v+Vout=0 is incorrect, the right one is 0v-3v-Vout=0. Try it, you won't get stuck again. Everything else is superb. Thank you.

wow excelent video....

@clarkken2148 3 года назад

perfectly lecture !

@goofypettiger 3 года назад

Just a general question here, what purpose does the 25k Ohm resistor from the amplifier's output to ground serve? I've seen circuits that have similar and the purpose escapes me. Thank you.

@VeritasEtAequitas 2 года назад

That represents the resistance of whatever the circuit is driving. IRL it could be a simple resistance like a light bulb or a complex impedance of a speaker.

Thank you.

@minhdiep1892 6 лет назад

why -3V/25K=0.12mA???? I think it is opposite

@srikrishna6122 4 года назад

What is it your are writting on? What's the name of that device?

@binaryparrot3352 3 года назад

I believe its called a glass pane :3

@davidglendaleardenaso8735 Год назад

shouldn't V2 be negative?

@ampudiauribemagdalena9023 Год назад

Merci beaucoup

@quantummandavid 4 года назад

Thanks bro.

@joanitarzzalwango6392 Год назад

The negative on vo is not there supposed to be there

@sibilakshman9575 7 месяцев назад

Cool video

@keynaanmedia5329 Год назад

Shouldn’t Vo= 3V instead of -3V

@joelhall649 6 лет назад

Thank you very much

@aliakbar4068 Год назад

please correction require Io = I3 +I2

@senanurkok2232 2 года назад

there is a mistake. i3 is minus 0.12 and i0 is 0.195 mA

@VeritasEtAequitas 2 года назад

Sorry, this video should have been redone. It's confusing and has errors. Passive sign convention!

@singlefather01 Год назад

I don’t understand why it is not -0.12mA…. Didn’t see the correction. Oops

Please can you tell me why "0V+ V40Kohm+V0=0" ?

bro the sounds from writing on that glass board or whatever makes me feel weird💀

@BenjaminProdLJB Год назад

The intro music is so loud

@joanitarzzalwango6392 Год назад

Vo is 3v not -3v

@parsa2007 Год назад

very helpful. you look like a very nice guy i want you hug you brother

@philosofsky123 День назад

Volume warning: the first 5 seconds or so are super loud 🔊🔊🔊

Lmao we lost about 5 minutes because of dancing with your intro.

How to calculate the currents easily, just apply the the Kirchhoff's rule of knots: i2 + i0 + i3 = 0 // i2 flows into the knot, so it's positive, i0 and i3 flows out of the knot, so they are negative 0.075mA +(-0.12mA)+(-i3)=0 // convert to i3 i3 = 0.075mA-0.12mA *i3 = - 0.045mA*
