Voltage divider calculator online
Compute Uout for given R1, R2 and Uin, or pick resistors for the required ADC/comparator input level.
Voltage divider
Classic resistive divider for calculating the output voltage or selecting the lower leg `R2`.
Output voltage
6.0000 V
Divider current
0.000600 A
Formula: Uout = Uin × R2 / (R1 + R2).
Frequently asked questions
How do I compute divider output voltage?
Uout = Uin × R2 / (R1 + R2) for the classic two-resistor divider. The calculator also helps pick values for a target Uout.
