Graphical Resistor Calculator
This JavaScript-based web app comes from my JavaScript Bible books (dating back to the very first edition with a few upgrades a long time ago). Although I have removed other book examples from this web site, this page remains the most popular destination within dannyg.com — presumably as a resource for students of electricity/electronics and my fellow radio geeks. Enjoy!
