Which term describes a circuit with a single path for current to follow?

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

Answer: (B)

A circuit with a single path for current is a series circuit. In this arrangement, all components are connected end to end, creating one continuous loop for electrons to flow from the power source back to itself. Because there’s only one path, the same current travels through every element, so adding more components increases the total resistance and changes the overall current according to Ohm’s law. If that single path is interrupted, the circuit becomes open and current stops. A closed circuit simply means the loop is complete; it can be either series or parallel, but the defining feature of a single-path setup is that it’s series. In a parallel circuit, by contrast, there are multiple paths and the current can split among them, which is the key difference.
