Ohms Law is probably the most frequently calculated equation in electronics, so a simple, quick and easy calculator for this equation is always useful.

After using my trusty calculator for the last 8 years to calculate resistor values for our customised LED light boards, I decided to write a simple Ohms law calculator to make the design easier and to help make standard resistor value selections. The application calculates the closest standard resistor values and includes a resistor color code chart.

I found this little application so useful and easy to use that I decided to share it with other electronics designers.

I hope you find this application useful.

If you have any comments, please send us some feedback so we can improve the application.
