Question

The given electrical network is equivalent to :

• A. OR gate
• B. NOR gate
• C. NOT gate
• D. AND gate

Answer 1

The Correct Option is B

To determine which logical gate the given electrical network represents, we need to understand the behavior of the different logic gates. Let's review the characteristics of each option provided:

1. OR Gate: The output of an OR gate is true if at least one of its inputs is true. The standard equation representing an OR gate operation is Y = A + B.
2. NOR Gate: A NOR gate is an OR gate followed by a NOT gate. Its output is true only when both inputs are false. The logic equation is Y = \overline{A + B}.
3. NOT Gate: A NOT gate inverts its input. If the input is true, the output is false and vice versa. The equation is Y = \overline{A}.
4. AND Gate: The output of an AND gate is true only if both inputs are true. Its equation is Y = A \cdot B.

Given the correct answer is a NOR Gate, we interpret this to mean the electrical network outputs true only if both inputs are false, aligning with the characteristic operation and equation for a NOR gate.

Conclusion: The given electrical network behaves like a NOR gate, matching the description that it inverts the inputs' OR operation. Therefore, the correct answer is a NOR Gate.
