Series Resistor Calculator

series resistor

Resistor is an passive electronic component that very commonly seen in electronic circuits. As the name suggest It is designed to resist/restrict the flow of electric current. Resistor is quantize by its resistance value, measured in ohms (Ω) which comes in various types / sizes / shape.

Even though the primary purpose of adding a resistor within a circuit is to control the flow of current, we can configuration resistor in various ways to create some complicated circuit. Which can be used in wide range of applications:

  • DAC – Digital to Analog Converter
  • Voltage Dividers
  • Current Limiters
  • Load Balancing
  • Sensing / Feedback Circuit
  • Biasing semiconductors

When resistors are connected in series, they create a sequential path for the flow of current. So, the total resistance of the resistors in series will be equal to the sum of the individual resistances. Use the below calculator to calculate the series resistance, just by giving the number of resistors in series with their respective resistance values, and this calculator will provide you with the total resistance.

Note : Don’t end with comma ( , )

Enter Resistance of All Resistors (E.g: 1,3,2,6,8,9,10,5)


\[ R = R_1 + R_2 + R_3 + R_4 + . . . \]

where :

  • R=Total Resistance
  • R1 ,R2,R3…=Each Resistance Value
