Resistor Combinations: Series and Parallel
Formula
Resistors in series add directly (R_total = R1 + R2), while parallel resistors combine as 1/R_total = 1/R1 + 1/R2. The parallel result is always less than the smallest individual resistor. These calculations are fundamental to circuit design.
Common use cases:
- Circuit design and prototyping
- Achieving non-standard resistance values
- Load balancing in power circuits
