In which of the following, output is similar to NAND gate if input A=0 and input B = 1.
Correct answer: C. XOR.
- A. NOR.
- B. XNOR.
- C. XOR.
- D. Both B and C.
Explanation
In logic gates, a NAND gate produces an output of 1 unless both inputs are 1. For inputs A=0 and B=1, the NAND gate outputs 1. An XOR gate outputs 1 when the inputs are different, which they are in this case (A=0, B=1), resulting in the same output as the NAND gate. Other gates like NOR and XNOR do not match this behavior with the same inputs.

About PN Junction
A PN junction forms when p type and n type semiconductor regions meet, creating a depletion layer and a potential barrier. The topic covers forward and reverse bias, diode current voltage characteristics, breakdown and rectification, while distinguishing an ordinary junction diode from a transistor formed from multiple junctions.
