Voltage Divider

Two 1k resistors and a 5V source create a 2.5V output on this voltage divider

A voltage divider uses two or more resistive elements to output a lower voltage than was input. This can have many functions, like allowing communications between devices operating at different voltages, and acting as inputs for devices that have variable resistance. After the break I’ll look at some of those uses, and cover the basic principles of voltage dividers.
