Which circuit is characterized by a single path for current?

• A. Open Circuit
• B. Short Circuit
• C. Series Circuit
• D. Parallel Circuit

Answer: (C)

Current must flow along a single continuous path without splitting. In a series circuit the components are connected end-to-end so there’s only one route for electrons to take from the source, through each element in turn, and back. Because there’s one path, the same current passes through every component; if any part of the path opens or breaks, the whole circuit stops conducting. This single-path arrangement also means the total resistance is the sum of the individual resistances. This is different from a parallel circuit, where the current splits into multiple branches, creating several paths.
