The Boolean expression X= A+B represents the logical operation of the:
Correct answer: C. OR gate
- A. NAND gate
- B. NOR gate
- C. OR gate
- D. NOT gate
Explanation
This is the correct answer. The given Boolean expression X = A + B represents the logical OR operation. In an OR gate, the output is high (1) if at least one of the inputs (A or B) is high. The '+' symbol in the expression denotes logical OR. X= A+B mathematically notation for OR operation

About Alternating Current
Alternating current varies periodically, so phase relationships become essential when current passes through a resistor, capacitor or inductor. The chapter distinguishes resistance from capacitive and inductive reactance, explains phase lead and lag, and connects changing electric and magnetic fields with the production and properties of electromagnetic waves.
