Three NAND gates are connected as shown in the figure.Which of the following logic gates is formed in the connected circuit?
Correct answer: A. OR
- A. OR
- B. AND
- C. NOR
- D. NAND
Explanation
We can check to which gate this diagram refers to by sending in 1 from A and 0 from B.Output at X, after working, will be 1. This means that this gate is working as an OR gate. Asonly in the OR gate, when two inputs are 1 and 0 respectively the output is 1.

About Electronics
A p-n junction forms when p-type and n-type semiconductor regions meet, creating a depletion layer, barrier potential and rectifying action. The work covers forward and reverse bias, junction current, diode characteristics, and how a diode converts alternating current into pulsating direct current through half-wave and full-wave rectification.
