text: One of the advantages of the potential divider compared to a variable resistor in series with the source is that, while variable resistors have a maximum resistance where some current will always flow, dividers are able to vary the output voltage from maximum (V S ) to ground (zero volts) as the wiper moves from one end of the potentiometer to the other.
