About this calculator

Overview

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

Pro Tips

Fun Facts

"Voltage dividers are used in potentiometers to create variable voltages."
"The output voltage is always less than or equal to the input voltage."
"Connecting a load to the output (Vout) will lower the voltage further (known as loading effect)."

Formula: Vout = Vin · R2 / (R1 + R2)
