Which circuit has multiple paths for current, and can still allow current if one path is obstructed?

• A. Open Circuit
• B. Parallel Circuit
• C. Series Circuit
• D. Static Electricity

Answer: (B)

When a circuit has more than one path for current, it is parallel. Each path runs directly from the power source back to the source, so the same voltage is across every branch. If one path becomes obstructed, the other paths still form complete loops and can carry current. In parallel, the current splits among the branches according to each branch’s resistance, but the overall circuit keeps delivering current where the paths remain closed. This is different from a series circuit, which has only one path; if that path is interrupted, all current stops. An open circuit stops current because there’s no complete loop, and static electricity isn’t about continuous current flow in a circuit. So the scenario described—current continuing to flow despite one path being blocked—fits a parallel circuit.
