Calculation of parallel or series connections
of two resistors in the series E24

If a resistor is not available as a standard value in the series E24, the series connection of two resistors is offered. The E24 basic series contains the following values: 10 Ω, 11 Ω, 12 Ω, 13 Ω, 15 Ω, 16 Ω, 18 Ω, 20 Ω, 22 Ω, 24 Ω, 27 Ω, 30 Ω, 33 Ω, 36 Ω, 39 Ω, 43 Ω, 47 Ω, 51 Ω, 56 Ω, 62 Ω, 68 Ω, 75 Ω, 82 Ω, 91 Ω. Possible resistor combinations can be calculated on this website.

The idea for this calculation was created when reading the article in [1]. There, the calculation of the parallel connection of resistors is presented with an Excel file.
