An electrical circuit where current flows through one path only is called

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

Answer: (D)

Current flows through a single path when the components are connected end-to-end from source to return, forming a series circuit. In a series setup, the same current passes through every component because there is only one path for the charges to follow. If any part of that path is opened, all current stops. This contrasts with a parallel circuit, where current can split among multiple branches; an open circuit has no complete path for current at all; and a short circuit creates a low-resistance path that bypasses the intended load. So the description describes a series circuit.
