What term describes a circuit that contains both series and parallel elements?

• A. Series circuit
• B. Parallel circuit
• C. Combination circuit
• D. Hybrid circuit

Answer: (C)

When a circuit includes sections where components share the same current (series) and sections where components share the same voltage (parallel), it’s described as a combination circuit. This label captures the mixed nature of the connections, unlike purely series or purely parallel setups. To analyze, reduce the circuit step by step: identify a group in series and replace it with its equivalent resistance, then find a parallel group and reduce that, and continue until you end up with a single equivalent resistance. For example, a resistor in series with two resistors that are in parallel can be simplified by first finding the parallel pair’s equivalent resistance, then adding the series resistor. This approach applies to any circuit that blends both connection types, which is precisely what a combination circuit describes.
