Solver for optimal voltage dividers using E24 and/or E96 series resistor values.

Voltage Divider Calculator

This program finds two-resistor voltage dividers created from real-world resistor values (EIA E24 and/or E96) with divider ratios closest to some target. Resistor tolerance and overall divider string resistance are taken into account. The calculator is a single .html file with inline Javascript.

Getting Started
