Electrical circuits provide pathways for electrical flow and include which configurations?

• A. Series and parallel.
• B. Direct current only.
• C. Only open circuits.
• D. No branches.

Answer: (A)

Electrical circuits provide pathways for electrical flow and include two fundamental configurations: series and parallel. In a series arrangement, components are connected end-to-end so the same current flows through every component, and the total resistance is the sum of individual resistances. In a parallel arrangement, components are connected across the same two nodes, so the voltage across each component is the same while the currents divide among the branches. These two layouts define how components share current and voltage, shaping how a circuit behaves. The other statements don’t describe how components are commonly connected: the type of current (DC or AC) is about the power source, not how components are arranged, and an open circuit or a single, non-branch path describes incomplete or special cases rather than the usual configurations.
