Operational Amplifiers discussion from start to the end of chapter...

[Mustehssun Iqbal]

Assalamu alaikum,
I made this thread so me and any other people can study Operational amplifiers in what is so called last minute study. I missed the first class of this chapter and the other, it flew over my head metaphorically :/
Now the approach is to read /study from the Physics application booklet and ask the terms and calculations I don't understand. I hope someone can cooperate in doing so. It can help in your revision too inshAllah.
P.S. I didn't post this in other threads of Physics and that of applications because this thread is for one topic separately.And I tend to study it from start to the end of chapter inshAllah...

What is meant by bandwidth??

issue solved

Bandwidth in Op-amps is the range of frequencies for which the gain is constant. Btw, make sure you search up the non-inverting amplifier in the book or on internet. The picture made in the booklet is wrong. In such an op amp, the input voltage is connecting to the V+ (non-inverting) and not to the V- as shown in the booklet. Secondly, the negative feedback from in b/w the two resistors is connected to V-.

Hope this helped.

lol! My booklet must be the old one then. :S

 

[Anneihtseme]

what is negative feedback guys ?
How does it connect with the other electronic component like Strain gauge, etc

i dunno but i have the old one too may be u're looking at the wrong diagram?

Both old and new have this one: [it's correct...right? or am i making mistake there?]

Its totally correct!

 

[OakMoon!]

This is totally correct. The one in my booklet is different. :S

u must be seeing the diagram for "inverting" amplifier...

No, I know what I'm talking about.
