The AND logic gate output is on only if ___________.

The AND logic gate output is on only if ___________.

• A. one input is on
• B. both inputs are off
• C. both inputs are on
• D. at least one input is on

Answer: (C)

The output of an AND logic gate is high (or "on") only when all of its inputs are high. In the case of a two-input AND gate, this means that both inputs must be on (or true) for the output to be on (or true). This fundamental characteristic defines how the AND gate functions in digital circuits and logic design. When both inputs are not on—whether one is off or both are off—the output will remain off. This ensures that the AND gate effectively operates as a requirement that all conditions (inputs) need to be satisfied for the output to be active, making it a critical component in various digital logic implementations.
