Voltage divider

A voltage divider (or potential divider) is a simple linear circuit that produces an output voltage (Vout) that is a fraction of its input voltage (Vin).

Voltage division refers to the partitioning of a voltage among the components of the divider.

An simple example of a voltage divider consists of two resistors in series or a potentiometer.

It is commonly used to create a reference voltage, and may also be used as a signal attenuator at low frequencies.
