Voltage Divider Calculator

Calculate the ideal voltage-divider output from the input voltage and two resistors.

Formula

Vout = Vin·R₂/(R₁+R₂)

Source / method note

Uses Vout = Vin·R₂/(R₁+R₂) for an ideal two-resistor divider.

Legal / official rate note

Load resistance, component tolerance, and power limits must be checked in a real circuit.
