11 Best Free Resistor Color Code Calculator For Windows

Here is a list of Best Free Resistor Color Code Calculator for Windows. All of these resistor color code calculators work on the same principle. Simply add color to all the bands in a resistor and get your answer. Different calculators in this list calculate resistor value of different numbers of band resistors, including 3 to 6 band resistors.

In this list, you will also find some calculators which feature both value to color and color to value conversions. The color to value conversion can be used to decode a color-coded resistor. On the other hand, value to color conversion lets you make a color-coded resistor by entering a resistance value.

Some resistor color code calculator software also let you calculate the resistance value of SMD resistors. Moreover, a PVIR (Power-Voltage-Current-Resistance) calculator is also available in some calculators. The PVIR calculator lets you calculate two of these measurements (power, voltage, current, and resistance) by entering other two measurements. In addition to this, some calculators also provide resistors standard values chart as per EIA (Electronic Industries Association) standards. These software also feature other useful calculators, like inductor calculator, Ohm’s law calculator, etc.

One of these resistor calculator software features resistor quiz. By playing this quiz, you can judge yourself in terms of resistor color decoding.

jRCaLc



jRCaLc is a free resistor color code calculator which is intended to do both color code to value and value to color code calculations for resistors. In both of these calculations, the color code scheme is applicable for 4, 5, and 6 band resistors. 9 different color bands are provided to add tolerance to the resistor. So that you can add tolerance to the resistors easily, the tolerance value (in percentage) is indicated on each color strip.

It displays the result immediately after filling colors in each band. The final result is expressed in three different units: Ohm, Kilo Ohm, and Mega Ohm.

In Value to Color Code calculator, you have to enter the required parameters in order to get a color-coded resistor. These parameters include resistance and tolerance values for 4 and 5 band resistors and temperature coefficient value for 6 band resistor.

Other features of this free resistance color code calculator:

  • With the help of PVIR (Power-Voltage-Current-Resistance) calculator, you can calculate the values of any two parameters by entering the values of other two parameters.
  • You can calculate the value of resistance of a maximum 10 resistors connected either in series or parallel.
  • Start to Delta conversion calculator is also available in the software.
  • Voltage Driver, Current Driver, and LED Resistor calculators are also provided.

Resistor Colour Code Solver



Resistor Colour Code Solver is a featured resistor value calculator which offers both color code to value and value to color code conversions. Both of these conversions are available for 4 band, 5 band, and 6 band resistors.

In this software, you have 8 color codes for tolerance level, which include brown, red, green, blue, violet, silver, gold, and grey. If you select 6 band resistor, you have to select the color for temperature coefficient. As you select color codes for each strip, that color becomes visible in the sample resistor on the interface.

The final result includes the value of resistor along with tolerance percentage. For 6 band resistor, the value of temperature coefficient is displayed separately. Not only this, you can also view the final answer in three formats, namely, normal form, exponential form, and in units.

Convert value to color code mode creates a color code resistor as per the set resistance value. This can be done by selecting the resistor parameters.

The PVIR (power-voltage-current-resistor) calculator of this software lets you calculate the values of any two electric parameters by entering other two parameters, just like jRCaLc.
