So the real value of this equation is that it allows us to calculate input resistance given the load resistance ? I don't really know how i should interpret it
@@anarchy3960 But is it the impedance that is inherently there ? Or does it mean i have to use lets just say resistors so the resistance on the input/output is chosen such that the equation is true ?
It is the input resistance and output resistance of the npn amplifier that we are calculating. This tells us how the system will be affected by the load and how the amplifier will affect the source signal.
Thank you! Please keep updating content about The Art of Electronics! The explanations are fantastic!
No problem. Thanks for the comment!

It's basically showing you that output impedance is reduced by Beta + 1 so you can drive more current/power to the load.

Oh wow! Beating Guinea. What an achievement. I'm sure that the FIFA Top 10 squads are shaking in fear!
