Output Voltage vs Input Voltage
Fórmula
## How a Voltage Divider Works Two series resistors produce an output voltage that is a fraction of the input. ### Formula **V_out = V_in x R2 / (R1 + R2)** The output is accurate only when load impedance is much higher than R2.
Ejemplo Resuelto
Divide 12 V using two equal 10 kohm resistors.
- 01V_out = 12 x 10000 / (10000 + 10000)
- 02V_out = 12 x 0.5 = 6.0 V
Preguntas Frecuentes
Can a voltage divider power a load?
Only very light loads. For substantial loads use a buffer or regulator.
How do I choose R1 and R2?
Pick the ratio R2/(R1+R2) for desired output. Keep total resistance appropriate for your application.
What if R1 and R2 are equal?
Output is exactly half the input voltage.
