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.
