**Potential (**is made up of two resistors. The output voltage from a potential divider will be a proportion of the input voltage and is determined by the resistor values.

*or voltage*) Divider**Operation:**

A potential divider works in the same way. Obviously a resistor is normally enclosed so you can't tap the voltage off at any point along it, so two resistors are used; the tap point being between these resistors. The diagram below shows a potential divider circuit with the standard component notation used:

*V*

_{1}is the voltage in and V_{2}is the voltage out.**Equation:**

*V*

_{2}= (R_{2}/ (R_{1}+ R_{2})) * V_{1}By rearranging this and specifying the total resistance (R

_{1}+ R

_{2}) the resistor values can be found from the desired output voltage V

_{2}.
