When two inputs are fed into an AND gate, what will the output be if only one input is HIGH?

An AND gate is a fundamental digital logic gate that outputs a HIGH signal only when all of its inputs are HIGH. In the case where there are two inputs, the AND gate requires both to be in a HIGH state for it to produce a HIGH output.

When only one of the inputs is HIGH while the other is LOW, the AND gate cannot satisfy the condition of having both inputs HIGH. Therefore, the output in this scenario will be LOW. This binary nature of logic gates ensures that they function based on clear truth values—HIGH typically represents a logic '1' and LOW represents a logic '0.'

The output being determined as LOW when only one input is HIGH aligns with the fundamental operational characteristic of AND gates, making this the correct answer.
