# Voltage divider

> Lowering the voltage value

\[202\] The next example I want to present in practice is a popular voltage divider. It allows the output voltage to be reduced to the desired value due to the properties described a little earlier.

![Eq. The output voltage at the divider](https://michalasobczak.pl/wp-content/uploads/2022/09/obraz-5.png)
*Eq. The output voltage at the divider*

Bearing in mind the above formula, we can assume that we want to reduce the input voltage of 5V to the expected 2.5V at the output. So we use two 1K resistors connected in series.
