Resistor combinations

Some times you might not have the resistor you need in your tool box or you need a non standard resistance value. Don't panic! You can replace the resistor with two resistors in series or parallel. The intention of this applet is to calculate the varius combinations and to print a list of the ones with the given maximum deviation.

Needed resistance:
Preferred values:


Best single resistor: Deviation:
