What would be the output of an AND gate if one of the inputs is logic "0"?

An AND gate operates under the principle that it produces a logic "1" (or true) output only when both of its inputs are also logic "1". When at least one input to the AND gate is a logic "0", the output will necessarily be a logic "0". This characteristic is key to understanding the functionality of digital logic circuits.

In digital design, the outputs of logic gates are defined clearly based on the inputs they receive. For an AND gate, the presence of a logic "0" indicates that the required condition for producing a logic "1" is not met. Therefore, regardless of the value of the other input, the output will be logic "0". This fundamental truth applies in various applications of digital circuits, reinforcing the reliability and predictability of logical operations.

Understanding this behavior is crucial for anyone studying digital electronics, as it forms the basis of constructing more complex circuits that rely on basic logical operations.
