JEE Main 2026 — 28 January, Evening Shift — Question 30

Two p-n junction diodes D1\mathrm{D}_{1} and D2\mathrm{D}_{2} are connected as shown in figure. A and B are input signals and C is the output. The given circuit will function as a ____\_\_\_\_ .

Question figure
  1. Option A:

    OR Gate

    Correct
  2. Option B:

    NOR Gate

  3. Option C:

    NAND Gate

  4. Option D:

    AND Gate

Answer: A

Step-by-step solution

If either A or B is zero, in that case current flow and vc=0\mathrm{v}_{\mathrm{c}}=0. Hence the Gate will be AND Gate
