Which circuit type has current that can split and flow along different branches?

• A. Parallel circuit
• B. Series circuit
• C. Short circuit
• D. Open circuit

Answer: (A)

Current can split when there are multiple paths for it to take. In a parallel circuit, each component is connected across the same two points, so the voltage across every branch is the same. The current from the source divides between the branches according to how easy each path is to flow through (its resistance): lower resistance draws more current. The total current supplied by the source is the sum of the currents in all branches, which is why parallel circuits can power multiple devices with the same voltage. In contrast, a series circuit has the same current everywhere and cannot split, because there is only one path for the current. A short circuit provides a very low-resistance route, causing a large current along that path, but it doesn’t describe splitting among branches. An open circuit stops current altogether because the path is broken.
