Voltage Divider Calculator

For two series resistors with the output taken across R₂, use the standard voltage-divider equation. Formula: Vout = Vin × R₂ ÷ (R₁ + R₂)

Input Voltage (V_in):

Resistor 1:

Resistor 2:

Output Voltage (V_out):

Calculate Voltage with a Divider

For two series resistors with the output taken across R₂, use the standard voltage-divider equation.

Formula: Vout = Vin × R₂ ÷ (R₁ + R₂)

Keep physical units consistent before applying the relationship. If the tool uses an assumed model, changing the model or a measured input can change the result even when the arithmetic is correct.

Check the units first, then substitute the same values into the displayed physical relationship to confirm the result.
