Voltage Divider Calculator

What is Voltage Divider?

Given voltage Vin as the input voltage; running Vin through resistors in series the output of the voltage between two resistor will drop by the radio of the resistors.

Let's see an example:

Using the formula for voltage divider:
Vout  =  R  * Vin
—————— ——————
We Get (lets take as example R1)
Vout  =  1000 Ω  * 9V
—————— ——————
2000 Ω
This results in Vout = 4.5V
