Resistors in Series Calculator
Resistors wired in series pass the same current through each one, and their resistances simply add together to give the total. This calculator sums any list of series resistors for you and returns the combined value. Series combinations are the easy way to build a resistance you do not stock, such as making a precise 1.5 kilohm value from a 1 kilohm and a 470 ohm part, or to divide a voltage across several components. Enter your resistor values in ohms, separated by commas or spaces, and the tool returns the total series resistance along with the count of resistors and the average value, which is handy when you are balancing a divider or a string. There is no limit on how many resistors you list. Everything runs locally in your browser, so results are instant and nothing is uploaded.
How to use Resistors in Series Calculator
- Enter the value of your first resistor in ohms.
- Add and fill a field for each further resistor in the chain.
- Read the total series resistance as the sum of all entries.
- Adjust any value to recalculate at once.
Frequently asked questions
How does the series resistor calculator find the total?
It simply adds every resistor value you enter, since resistors in series carry the same current and their resistances sum directly.
Is the series total always larger than each resistor?
Yes, each added resistor increases the total, so the series resistance is always greater than or equal to the largest single resistor.
Does resistor order matter in a series string?
No, series resistance is a plain sum, so the order of the resistors has no effect on the total value.
