Potentiometer Taper Charts

Linear Taper

$R$ = total resistance of the potentiometer, measured between the potentiometer hot and cold lugs

Resistance vs. Percent Rotation:

Audio Taper

$R$ = nominal resistance of the potentiometer, measured between the potentiometer hot and cold lugs

Resistance vs. Percent Rotation:

Audio Taper (No Load)

"No Load" - hot lug is disconnected from the resistive track, resulting in an open circuit at full rotation.

$R$ = nominal resistance of the potentiometer, measured between the potentiometer wiper and cold lugs

Resistance vs. Percent Rotation:

M and N Taper (Blend-Balance)

$R$ = nominal resistance of the potentiometer, measured between the potentiometer wiper and cold lugs (M for top pot, N for bottom pot)

Resistance vs. Percent Rotation:

M and N Taper (Blend-Balance)

$R$ = nominal resistance of the potentiometer, M (top pot) measured between the potentiometer wiper and cold lug, N (bottom pot) measured between the potentiometer wiper and hot lug

Resistance vs. Percent Rotation:
