If two inputs of a NAND gate are connected together, then the resulting truth table will represent the characteristics of a/ an

Correct answer: B. NOT gate

  • A. OR gate
  • B. NOT gate
  • C. AND gate
  • D. XNOR gate

Explanation

When the two inputs of a NAND gate are connected together, the gate behaves like a NOT gate. This is because a NAND gate outputs false only when both inputs are true; if both inputs are the same, it inverts that input. Therefore, the correct answer is NOT gate. The other options are incorrect because they describe behaviors that do not match the NAND gate under these conditions. An OR gate requires at least one true input to output true, an AND gate requires both true inputs to output true, and an XNOR gate outputs true only when both inputs are the same, which isn't applicable here.

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.
