If a circuit has no branches, what type is it?

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

Answer: (D)

Having no branches means there is exactly one path for current to flow from the source through all components back to the source. A circuit with a single path is a series circuit. In a series circuit, the same current travels through every component because there’s nowhere else for it to go. If there were branches, the current would split, which describes a parallel arrangement. An open circuit would break the path entirely, and a short circuit creates a low-resistance bypass, neither of which describes a single, uninterrupted path. So, the circuit with no branches is a series circuit.
