What is the output of an OR gate when both inputs are low?

• A. High
• B. Low
• C. Unknown
• D. Floating

Answer: (B)

An OR gate is a digital logic gate that outputs a signal based on its inputs. Specifically, it produces a high output (1) when at least one of its inputs is high (1). If both inputs to the OR gate are low (0), the only possible output is low (0). This characteristic is what defines the behavior of an OR gate. When assessing the scenario where both inputs are low, neither input can contribute a high signal, resulting in the gate's output remaining low. Therefore, the correct response indicates that the output is low when both inputs are in a low state.
