    • ANAND gate
    • BNOR gate
    • CAND gate
    • DOR gate
    Show answer & solution

    Correct answer: (B)

    When the output of an OR gate is applied as input to a NOT gate, then the combination acts as NOR gate.
  2. NEET 2023Mediump-n Junction Diode
    Q2
    Given below are two statements:
    Statement I: Photovoltaic devices can convert optical radiation into electricity.
    Statement II: Zener diode is designed to operate under reverse bias in breakdown region.

    In the light of the above statements, choose the most appropriate answer from the options given below.
    [NEET 2023]
    • ABoth Statement I and Statement II are incorrect
    • BStatement I is correct but Statement II is incorrect
    • CStatement I is incorrect but Statement II is correct
    • DBoth Statement I and Statement II are correct
    Show answer & solution

    Correct answer: (D)

    Both Statements are correct. I: Photovoltaic devices convert optical radiation into electricity. II: Zener diode is designed to operate under reverse bias in breakdown region. e.g., Zener diode as a voltage regulator.
  3. NEET 2023EasyDiode as Rectifier
