Chapter 1

No. $R_{O}$ is in series with $R_{L}$ , so if $R_{L}$ gets smaller, there will be a smaller voltage drop over $R_{L}$ and a larger voltage drop over $R_{O}$

21, F1.18: Why does it have to have an source impedance? How big is this impedance? Loading effects? Could we get rid of this if we had superconducting wires?
31,1,5: Why are the output resistances placed where they are? It seems there would be a voltage drop over the voltage amplifier and extra current not being accounted for in the current amplifier?
