In a simple circuit, which configuration yields higher current capacity?

• A. Series
• B. Series-Parallel
• C. None
• D. Parallel

Answer: (D)

When considering how much current a circuit can safely carry, the arrangement matters a lot. In a series setup, the same current flows through every component, so the whole circuit’s current is limited by the component with the smallest current rating. You can’t push more current through the chain just by adding more components in series. In a parallel setup, each branch has the same supply voltage, and the current splits among the branches. The source must provide the sum of the currents in all branches, so adding more parallel paths increases the total current the circuit can deliver. That’s why parallel configurations yield the higher current capacity. The mixed series-parallel arrangements don’t reach the same total capacity as a full parallel setup for the same supply and loads.
