    I'm currently studying about transistors and I would like some guidance on this part
    where an amplifier has this kind of circuit

    For the DC Equivalent Circuit
    The potentiometer would be a fixed resistor and the capacitor would be open and would result to a circuit of

    On an AC Equivalent Circuit
    the capacitor would be shorted. However I can't seem to understand how would the potentiometer act on this circuit

    You need to replace the potentiometer by two resistors that add up to the value of the potentiometer. Using a single resistor represents only the special case with the wiper in the top position.
