๐งฉ Resistor Series/Parallel Calculator
Total resistance50 ฮฉ
Enter the values of multiple resistors to calculate the total (equivalent) resistance when connected in series or in parallel. Add or remove resistors freely.
How to use
- Choose series or parallel.
- Enter each resistorโs value (ฮฉ). Use "Add resistor" to add more.
- The total resistance is calculated automatically.
FAQ
What formulas are used for series and parallel?
Series is the simple sum of resistances (R = R1 + R2 + ...). Parallel is the reciprocal of the sum of reciprocals (1/R = 1/R1 + 1/R2 + ...).
What happens to total resistance in a parallel circuit?
The total resistance of a parallel combination is always smaller than the smallest individual resistor value.
How many resistors can I add?
You can add as many resistors as you like using the "Add resistor" button โ thereโs no upper limit.
