Using only resistors in the e12 , e6 , e3 and e1 ranges of resistors, the calculator will find a pair of resistors which can be used to create a resistance which is the closest match to that required, and will also report any better match which can be obtained. Voltage divider resistors can be from 0.1 ohm to 999mohm.
