What are the two basic types of electrical circuits?

• B. Series and complex
• C. Parallel and mixed
• D. Direct and alternating

Answer: (A)

Two basic ways to connect electrical components in a circuit are in series or in parallel. In a series arrangement, there’s a single path for current; the same current flows through every component. The total resistance is the sum of the individual resistances, so adding more components increases the overall resistance and reduces the current for a given supply. The voltage is shared among the components, with each drop proportional to its resistance. In a parallel arrangement, each component is connected across the same two points, so the voltage across every branch is the same as the source. The currents in the branches add up to give the total current, meaning the overall current increases as more parallel paths are added. If one branch is removed or fails, the others continue to operate because other paths still supply current. The other terms describe how current behaves rather than how components are arranged, so they don’t reflect the two fundamental circuit connection types.
