Which logic element describes a circuit with two normally open switches in series?

Explanation:
Two normally open switches in series implement an AND relationship. Each switch is off by default, meaning no current flows until it’s actuated (closed). In a series path, current can pass only if both switches are closed, so the circuit conducts only when both inputs are true. That aligns with the AND behavior: output is on only when all inputs are on. If either switch stays open, the path is broken and the output remains off. This differs from an OR arrangement (which would use parallel paths so that one closed switch can complete the circuit) and from NAND or NOR (which invert the result of AND or OR, respectively).
