Resistors have color codes that help people determine their respective values and tolerances. However, mastering all the color codes requires significant investment in terms of effort and time. Fortunately, ResCalc Master allows anyone to determine these values easily. The simple resistor calculator is designed for all people who use resistors irrespective of their level of electronic knowledge.

ResCalc Master's Features

  • EIA standard value table
  • Color code table with decoding example
  • Supports resistors with between three and six bands
  • The latest version supports LED resistors
  • Automatic checking of updates

Using ResCalc Master

ResCalc Master is designed for 32-bit Windows operating systems, and it is compatible with Windows 2000 upwards.

The program allowed us to do different things, including:

  • Determining the values of resistors depending on their colors
  • Determining the colors of resistors based on their respective values
  • Determining resistor standards depending on their values

We could also determine the total value of resistors depending on their connections. While you may know how to calculate the values of resistors connected in either series or parallel, the calculations take some time. With ResCalc Master, you only need to enter the respective values of the resistors and press the 'Calculate' button to get the answer you want.

We started our calculations by selecting the number of bands the resistors had. We then selected corresponding colors, and the program automatically displayed the values on the top right part of its interface. It also displayed a graphic representation of the resistors, which made it easy for us to confirm that we had selected the right colors. We simply compared the resistor with the image displayed to determine whether they were similar or not.

We performed reverse calculations by entering values of resistors, and the program displayed their appropriate color codes. This feature can come especially handy to amateurs who want to get the right resistors for their projects.

ResCalc Master is also ideal for people who want to learn resistor color codes. The included color code table makes it easy for newcomers to understand how to make calculations. It includes a six-band resistor decoding example that helps in explaining how to determine values, including tolerances and temperature coefficients. The calculator also shows how resistor orientational dimensions are dependent on the strength of dissipation.


ResCalc Master is a powerful resistor calculator that makes it easy for anyone to determine the values of resistors based on their color codes or vice versa. It is also a great tutor for anyone who wants to master the resistor color code.

"works pretty well, except for install issues"

Pros: Once it works, it works very well

Cons: Once I select an optional band (such as Tolerance), there's no way to turn it off and return to default setting.

Other Thoughts: I had the same experience that others have reported, with the default 32-bit installer; it will not install on a 64-bit Windows platform. I've built many 32-bit programs with MinGW and other build platforms, and they have all installed and run just fine on 64-bit machines; don't know what the issue is with this one.

However, once I installed the 64-bit version of the program, it installed and ran fine. This would be a handy program for someone just learning their color codes.
