10K Potentiometer 15mm Shaft

10K Ohm 3Pin 15mm Shaft Potentiometer It is a 10K Ohm 3Pin 15mm Shaft Potentiometer. This is used for adjusting various parameters like voltage, current, etc in an electronic circuit. If you turn or slide it halfway, its resistance will be halfway between its minimum and maximum settings. That’s ideal for controlling lights or a fan, but not necessarily for audio controls. Volume controls have to cater to the human ear, which isn’t linear. Instead, logarithmic pots like this one increase their resistance on a curve. At the halfway point volume will still be moderate, but it will increase sharply as you keep turning up the volume. This corresponds to how the human ear hears. Using a log pot, therefore, gives the effect that a setting of full volume on the control sounds twice as loud as a setting of half volume. A linear pot used as a volume control would give large apparent changes in loudness at low volume settings, with little apparent change over the rest of the control´s range.
