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

The logic element that describes a circuit with two normally open input switches in series is indeed the AND gate. When the input switches are normally open, they will only allow current to flow, or provide a high output, when both switches are closed. This reflects the fundamental behavior of an AND gate, which requires all inputs to be true (or ON) for the output to also be true.

In the context of this scenario, if one switch is closed and the other remains open, the overall output remains low. Only when both switches are closed does the circuit complete, resulting in a high output. This concordance with the function of an AND gate demonstrates why it is the correct choice. For clarity, NAND, NOT, and NOR gates represent different logical operations and do not align with the requirement that both inputs must be active to produce a true output.
