Potentiometer Equation and Calculator.

A potentiometer or a resistor a pot, is a three-terminal resistor with a sliding or rotating contact that forms an adjustable voltage divider. If only two terminals are used, one end and the wiper, it acts as a variable resistor or rheostat.

Tolerance  %
R1  Ohms
R2  Ohms
Input (Vin)  Volts
Output (Vout) = V / (R1 + R2) x R2
Output =  Volts  
Maximum =  Volts   
Minimum =  Volts
