Potentiometer Voltage Divider

Description

Potentiometer is a three-terminal resistor with a sliding contact that forms an adjustable voltage divider. The potentiometer can be used as a voltage divider to obtain a manually adjustable output voltage at the slider (wiper) from a fixed input voltage applied across the two ends of the potentiometer. The voltage across Ro can be calculated by the resistances and the sourse voltage.
