Calculate the total equivalent resistance of resistors connected in series. In a series configuration, the same current flows through all resistors.
Enter your values below
First resistor value.
Second resistor value.
Optional third resistor. Leave blank to ignore.
How this calculator works
In a series circuit, the total resistance is the sum of all individual resistances. The total resistance is always greater than any individual resistor.
