Question:

Options:

a

b

c

d

Correct Answer:

d

Explanation:

A and B are inputs and C represent the output.

If we apply some positive voltage across AB,then diode corresponding to A will be on and the other diode will be off
⇒ Output C=A
If the applied voltage is negative then diode corresponding to B will be on and the other diode will be off
⇒ Then Output C=B
We can say that C=oB
Therefore it acts like OR gate.
