Calculation of parallel/series connections
of up to five resistors E12

In the meantime are resistors avaiable of the series E24 and E96 with tolerance of 1 % relativ inexpensive. So the usuable 24 or 96 values in each decade, which have at one's disposal, shold be sufficient for homebrewer. But if one need resistors with higher power dissipation or with reduced tolerance, one can fall back only on resistors of other series. On this webpage you can calcute the nonexistent values as results of the parallel or series connections of up to five resistors. For unused resistors select ---.
