resistors
A collection of algorithms helping to calculate the properties of resistors. E.g. find the closest value of a standard resistor within a given error margin for a resistance needed. The tool will tell you the standard value and the first standard series in which it was found. Voltage dividers can also be calculated, for a given in- and output voltage the tool will find any possible combination of resistors.
