RESISTOR CALCULATOR (Courtesy of Northstead Design Ltd.)
You know the exact resistance you want in your circuit but can it be done with just one resistor or with
2 resistors either in series or parallel?
Why mess around for ages with your calculator trying to find the best option?
This calculator calculates the required Parallel Resistors and Series Resistors of the E12, E24 and E96 ranges
and the actual value and error in order to get the nearest combinational match to the users requested resistor value.
If there is an exact match with one resistor, the second resistor will show N/A (Not applicable)
If a single resistor will give a closer match then the second resistor will show N/A
Enter the required Resistor Value in ohms in this box (no K M or m, just a number):
ohms
