When you turn down or up the volume on devices with either a wheel or button, what actually happens that allows it to sound quieter or louder?
In: Technology
Sound travels through your electronic device as a very small electrical current. Think of this current as “flowing” like water.
When the volume knob is all the way up, all of the water is allowed to pass through it, but as you turn the knob down, less and less water is allowed through. The amount of “water” coming through = volume.
