When putting resistors in series the total resistance value needs to be calculated. This handy resistor calculator will help you do that.
In a series circuit the same amount of current passes through all the resistors. This means the total resistance is equal to the sum of all of the resistors added together. The series resistor calculator sums the value of each resistor and outputs a total resistance value.
The formula for calculating series resistance is: R = R1 + R2 + R3 + R4 + Rn
Rn is for extrapolation. If you have more than 4 resistors, just keep adding them up by changing Rn to R4, R5, etc.
