How this calculator works
Enter the values for first value, second value and review the units before calculating.
Formula / method
Vout = Vin × R2 ÷ (R1 + R2)
Worked example
12 V with equal 10 kΩ resistors gives 6 V unloaded output.
Assumptions and limitations
The output load is negligible compared with the divider resistance.
A connected load changes the result; use a loaded-divider analysis for real circuits.
