Which circuit is defined as having multiple paths for current that allow flow even if one path obstructed?

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

Answer: (B)

The idea being tested is that circuits with multiple paths for current allow flow even when one path is blocked. In a parallel circuit, each branch provides its own route from the power source back to the return. If one branch becomes obstructed, current can still flow through the other branches, so the circuit remains closed and components in those branches can stay powered. This contrasts with a series circuit, where there is only a single path for current; blocking it stops the entire current flow. An open circuit is simply a break that prevents current from flowing at all, and static electricity concerns charge buildup rather than sustained current through a circuit.
