### What is relevance of Norton's theorem over Thevenin's theorem

I am well aware of the importance (more appropriately, implication) of Thevenin's theorem in real-life circuits. Output impedance of amplifiers and the 'stiffness' of a power supply (such as the ...

### Thevenin equivalent (verification of answer)

$R_{TH} = R1 + R2//R5 + R3//R4$ Then considering the current source and the resistance R3 as a Norton circuit, one can convert it to Thevenin as follows $V_I = -IR3$. Then we have the voltage ...
I have the above circuits and I have some questions related to them: I drew above the Norton and Thevenin equivalents where $R_{no}$ is the resistance of the whole amplifier circuitry, excluding ...
