Electrical Engineering: Ch 5: Operational Amp (8 of 28) Summing Amplifier (Non-Inverting)

In this video I will explain the non-inverting operational amplifier as a summing amplifier.

Next video in this series can be seen at:

i just need to comment on my appreciation again, you are so humble with your explanations, so precise and straight to the point.

[oskarlind]

Nooo, I need more of these videos :( Please make more as son as possible because I find them very educational and the quality is supreme. Keep up the good work!

[kaursingh]

sir -- your each and every lecture is the very best on internet -- short , simple and to the point --thank u sir

[arthurkaranja]

Hey prof thanks .Your explanation and derivation was simple and clear .Really helped me in my exams.

[affection]

it was one of the best parametric op amp questions I ve ever seen.

thank you sir

[reubenwilliammpembe]

you are the best Sir!!!

hey, ,
can you do a video about butterworth filters "second and forth order" please
Best Regards

Do R1, R2, R3 have different values? Does Rf have different values than R1, R2, R3?

[paulktemplar]

in the previous video u made Va approx 0, why didn't u try that here? Thanks for your help.

[davidglendaleardenaso]

is this non-ideal like Va and Vb aren't equal to 0?

[phoenix]

hey prof, i have just finished high-school, am i ready to start from chapter one with the electrical engineering classes you have ?
or should i study something before that.
i am following this chapter about opAmps and i can understand most of the things.

I think 1/R1 + 1/R2 + 1/R3 is not the same as 1/RT, since adding fractions is not the same as adding whole numbers.

[haileypong]

Sir, you never fail to save me in my exams. Thank you!

[candycandy]

Do you always buld the equation using high potential - low potential?
In Video 3 you did it differently. I am really confused :(

[monemahmed]

hey man! please try to write on the board in a way such that camera can see what you are writing. don't be a wall between these.

[tanjidhossain]

sir i cant find electrical engineering playlist

[Jarrod_C]

again, use case of this?when in real life would we use a summing amplifier? Importance, use case, trade offs, etc.. Needs to be a translation to industry use.

[eggxecution]

Ohhh I thought all the currents are entering and no one is leaving it turns out the one that is leaving is I=0 LOL

[nawelouahrani]

Thank you sir, you're a genius !

[rubaiatislamprotik]

Why is I_f + 0 = I_i? Why is the non-inverting terminal 0?
