Multiple Choice

Two normally open switches in series implement which logic operation?

Two normally open switches in series behave like an AND operation. In a series path, current can flow only if both switches are closed. Since these switches start open and only close when actuated, the circuit completes (output on) only when both switches are activated. If either one remains open, the path is interrupted and the output stays off, matching the true/false rule of AND: true only when both inputs are true. If the switches were in parallel, the output would go on if any one switch closes (like OR). NAND or NOR would require an inversion after the result.
