Question

In the circuit as shown in figure, A and B represent two inputs and C represents the

• A. OR gate
• B. NOR gate
• C. AND gate
• D. NAND gate

Answer 1

The correct option is A OR gate

The circuit represents OR gate, as the output at C is 1, when either A or B or both A and B have input at level 1. But output at C is zero, when both A and B are at zero level and the Boolean expression is C = (A + B).
