Frequently Asked Questions
The equivalent resistance of resistors in parallel is given by 1/Req = 1/R1 + 1/R2 + ... + 1/Rn. Then Req = 1 / (sum of reciprocals).
Zero ohms would represent a short circuit, making the equivalent resistance zero. The calculator will show an error because it is not a valid resistor value.
This calculator supports up to 5 resistors. For more, you can use multiple calculations or a more advanced tool.
