Resistance Compositor

Resistance Compositor is a Java-based software utility designed to give you a helping hand in replacing resistors by calculating the best possible combination.
Broken resistors can be replaced with a mixture of two parts ordered in series or in parallel. This tool supplies you with the list of possible combinations to replace while maintaining the same output. It can be easily used to deliver quick results.

Simple GUI for calculating resistance

It's wrapped in a user-friendly interface made from a single window with a clear-cut structure, giving you an overview of all options available. All you have to do is enter the resistance and maximum difference (percentage) in two fields, pick the series between E12 and E14, as well as perform calculations with one click.
Results are immediately shown in a table, which shows the difference, resistance and description. Unfortunately, the application doesn't implement buttons for printing or exporting all information to file for closer inspection and safekeeping. On the other hand, you can select one or more rows to copy data using the global keyboard shortcut.

No setup required, besides Java

Provided that you have Java installed on your machine, you don't need to set up anything else. The entire program's packed in a single executable .jar file that can be saved to a custom directory on the HDD or copied to a USB flash drive to seamlessly run Resistance Compositor on any PC with Java. It doesn't change system registry settings, or create files on the disk without your approval.

Evaluation and conclusion

Calculations were swiftly made in our tests while the tool remained light on system resources consumption. No error dialogs popped up and it didn't hang or crash. Thanks to its straightforward options, Resistance Compositor can be used with ease.
