Which circuit has multiple paths?

• A. Three-phase power system
• B. Direct current flows one direction
• C. Electrical pressure pushing current
• D. Circuit with multiple paths

Answer: (D)

Multiple paths in a circuit means the current can travel through more than one route between the power source and the load, which describes a parallel arrangement. In this setup, all branches have the same voltage across them, and the current splits among the branches according to each path’s impedance. Because current can take several routes, the total resistance is lower than any single path, providing redundancy—if one path fails, current can still reach the load through the others. The option that describes a circuit with multiple paths best captures this idea. The other statements refer to the direction of current, the mechanism driving current, or a broader system context, but they don’t describe branching paths in a circuit.
