The figure above shows an amplifier model (using a voltage-controlled voltage source). Notice
that, this is just one way to model an amplifier. There are different types of models of an
amplifier but all models give the same input-output characteristics. You can simply obtain other
models by using Thevenin Norton conversion. We want to connect a signal source (AC, DC or a
combination of them) to the input of our amplifier and a load resistor R1 to the output of our
amplifier as shown by dashed lines. Rin is the input resistance, Rout is the output resistance and K,
is the voltage gain parameter of the amplifier.
a) Find an expression for Veu V, (i.e. voltage gain from signal to load) using given parameters
