Diodes connected in parallel would act like an
- an NAND gate.
- an AND gate.
- an OR gate.
azfar92 asking:
Why is the answer AND gate? For example,you put 2 diodes parallel to each other. If the current flow through one of the diodes,wouldnt the circuit is still complete?

Hello.
I agree with you. Changed to "OR".

With all due respect, please don't miss-guide the peoples.
Answer has to be an AND gate in this case, if you want to know more send me a free subscription ;)
P.S: There are no diagrams given for this question.

Hello MridulDev.
There is no additional information about how this diodes are biased, do they have additional power source and so on... So, just electrically, if we have two diodes connected in parallel, they act as OR gate, until there is no additional info. This is my IMHO.
Sure, if study more deeply how AND gate is implemented, we see what they are connected in parallel indeed, but there is some more additional details. :)
If azfar want to to get some info, check this: http://en.wikipedia.org/wiki/Diode_logic

Can you share a figure of two diodes in parallel then, to be more clear :)

Check link what I gave. :) There are two figures, for AND and OR gate. In both figures they are connected in parallel but in AND gate they are reverse biased and pulled up. :)

question should specify.....diodes connected in parallel and forward biased....i think
