Which term describes a circuit that contains both series and parallel sections?

• A. Series
• B. Parallel
• C. Series-Parallel
• D. Mixed

Answer: (C)

A circuit that has both series and parallel sections is described as a series-parallel network. This means there are parts arranged in a single path end-to-end (a series chain) and, at the same time, other parts connected across the same two nodes so current can split through multiple paths (parallel branches). That combination is exactly what series-parallel describes. This is more precise than just calling it mixed, which is vague. Pure series would mean everything lies in one uninterrupted line with no branching, and pure parallel would mean every element sits directly across the same two nodes with no chain-like connections. In a series-parallel circuit you can identify a series group and a parallel group and simplify step by step by replacing those groups with their equivalent resistances (or impedances) until you reduce the circuit. For example, if two resistors are in series, their combined resistance adds; if that pair is in parallel with another resistor, you would then combine that parallel group, and so on. This step-by-step reduction is typical for series-parallel networks.
