Which circuit is described as having multiple paths; electricity will not flow if there is an obstruction?

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

Answer: (C)

Electric current needs a closed loop to flow. In a series circuit, all components sit along one single path from the power source back to the other terminal. If anything in that path opens the loop—like a broken wire or a switch that’s off—the circuit becomes incomplete and current cannot flow at all. That means electricity stops everywhere in the circuit because there’s nowhere for the electrons to go. The idea of multiple paths belongs to parallel circuits, where breaking one branch doesn’t necessarily stop current in the others. Here, with a single path, any obstruction halts the whole circuit.
