Voltage Divider Formula
Output voltage from two resistors connected in series across an input voltage.
Formula
Vout = (Vin × R2) / (R1 + R2)
Discipline: Electrical. Result unit: V.
Variables and units
- Vout — Output Voltage (V): Voltage across the lower resistor
- Vin — Input Voltage (V): Supply voltage
- R1 — Upper Resistance (Ω): Resistor connected to the input side
- R2 — Lower Resistance (Ω): Resistor connected to ground/reference
