This is a picture of what kind of circuit?

• A. Series
• B. Parallel
• C. R-C
• D. Open

Answer: (A)

In a series circuit, all components share a single path for current. The current that flows through each element is the same because there’s only one loop. The picture shows components connected end-to-end in one continuous loop with no branches, which is the classic layout of a series circuit. That single path is what distinguishes series from other layouts: parallel would show branching with multiple paths, an R-C setup would include a capacitor, and an open circuit would show a break in the path. So the image reflects a single-path, series arrangement.
