A series-parallel circuit is formed by connecting a set of parallel resistors in series.
- Connect R_1 and R_2 in parallel to obtain an effective resistance of R_{P1}.
- Similarly, connect R_3 and R_4 in parallel to get an effective resistance of R_{P2}.
- These parallel segments of resistors are then joined in series.

Series-parallel combination of resistors
The formula for the effective resistance of the parallel combination of resistors is
For two resistors in the circuit, the effective resistance is given as
Using the effective resistance of the series circuit, , the net effective resistance of the series-parallel combination of resistors is,
Parallel connection of series resistors:
A parallel-series circuit is formed by connecting a set of series resistors in parallel.
- Connect R_1 and R_2 in series to get an effective resistance of R_{S1}.
- Similarly, connect R_3 and R_4 in series to get an effective resistance of R_{S2}.
- These series segments of resistors are then joined in parallel.

Parallel-series combination of resistors
