How the calculation works
Calculate output voltage and current in an unloaded resistor divider. The tool converts the form units and presents the result using readable engineering notation.
Vout = Vin × R₂ / (R₁ + R₂)
Example
12 V with R1 10 kΩ and R2 10 kΩ gives about 6 V unloaded.
How to interpret the result
- The basic equation assumes the output is not significantly loaded.
- A load resistance appears in parallel with R2 and changes the result.
- For ADC inputs, check source impedance and sampling time.
Limitations and safe use
The result uses a simplified model. Check tolerance, temperature, absolute ratings and the component datasheet.
FAQ
Is the result saved?
The latest result may be stored locally in this browser, but it is not sent to LutujTo.
Can I use the result in a project?
Yes, but select a real component with margin and confirm its ratings in the datasheet.
