The Volume Knob Is A Attenuated Switch That Does Not Amplify Sound.
Jul 10, 2018

It is often said that the volume knob is a attenuation switch, that is, it cannot amplify the sound. What is the matter?

It's very simple, structurally: the volume switch is VR. It's called a voltage divider on a circuit: what's a voltage divider? The simple answer is to take the required Y out of an input voltage assumed to be X and then import the unused Z into the ground. We can see from the graph that although the cases of Y and Z can change indefinitely, the sum must be equal to X.
