Resistor finder
Finds a combination of two series or parallel connected resistors for a custom value. Returns a list of the best values found.
| Example 1: Must calculate the combination of 1% resistors to produce a resistance of 66 kilo-ohms | View example |
You may use one of the following SI prefix after a value: p=pico, n=nano, u=micro, m=milli, k=kilo, M=mega, G=giga
| Configuration | Resistor R1 | Resistor R2 | Total resistance | Error-% |
| Series | 5.1 kilo-ohms | 3.6 kilo-ohms | 8.7 kilo-ohms | 0% |
| Series | 7.5 kilo-ohms | 1.2 kilo-ohms | 8.7 kilo-ohms | 0% |
