Resistive voltage divider

Calculates resistors of the voltage divider network automatically. Assumes the required output current to be negligible.

Example 1: Must calculate the resistors for a 5V to 1.25V voltage divider using 1% resistor seriesView example

You may use one of the following SI prefix after a value: p=pico, n=nano, u=micro, m=milli, k=kilo, M=mega, G=giga

Fill in all the fields. The result will be a list of best matches found.
  • Input voltage - Known input voltage
  • Output voltage - Required output voltage with the given input voltage
  • Resistor series - Resistor E-series of where to choose resistors from
  • Min resistance - Minimum value of the resistors (can be 1ohm-100Mohm)
  • Max resistance - Maximum value of the resistors (can be 1ohm-100Mohm)
