My wording of the question could be confusing as I am trying to learn rather than stating something I know. But I came across this concept multiple times - that the voltage required to turn on the diode is supplied by the OpAmp rather than by the small signal. That is the reason why the...

Right off the bat, V_b is fixed by a voltage divider consisting of R_1 and R_2. In other words, V_b is the voltage drop across R_2 only. If you combine them in parallel then what you obtain is Thevenin equivalent resistance that you would place along with Thevenin voltage which is, in turn...

Hi all, I am currently studying OpAmps and one of the topics that came up was the applications of OpAmp circuits. In particular, I was learning about precision rectifiers (using non-inverting version of it, thus the diode is pointing away from the "out" terminal of the OpAmp). The thing I...

Thank you all for the replies! It's starting to make sense now. The question that made me think about this involved a rod attached at one end and a force acting at the other end. In other words, both the center of mass and the endpoint of the rod trace a circular path, however due to the radii...

I am having trouble understanding the concept of work on an intuitive level. The equation is rather simple but the definition of displacement is vague (everywhere I looked it's just stated as displacement of the body in the direction of motion). The question is, is this the displacement of the...
