... Firstly we need to determine the output voltage of the first op amp, which can be labeled as v1 . There is zero voltage across the two input terminals of the ideal op amp. So the inverting terminal voltage should be equal to that of the non inverting terminal. That is 2V. The input currents should b ...

... We have designed a circuit for which the output is the same as the input. So what? Well, this circuit is most frequently used as a buffer where the high (infinite?) input impedance will not act as a drain on the source of the signals. For example, a simple photodetector could be made using a photodi ...

Maximum Power Transfer in a Circuit
... This derivative is equal to zero when R = Rint. From the above discussion it is clear that the derivative is zero here because this is the value of the resistance R at which the power P is a maximum (as opposed to say a minimum).
