AND gate using BJT transistors, LED delivers output only when two transistors were power supplied i.e., at logical levels 1 &1.

And what happens to output when one or both inputs are 0?
lenzrulz

Both transistors must be saturated “ON” for an output at Q, so if inputs A and B are both at logic 0 then output Q would be 0, I thought that much was obvious?

The reason why I asked sumanth33 this question was to make him think about. Something which lenzsux obviously didn't do, because his answer is wrong.

Stop toying with members, help them with corrective examples or bypass their circuits.

Go play with your own crap, don't play tech savvy and trumpet around wrong answers to other people circuits.

Check out the truth table and then continue spewing your usual fallacious narrative that my advice is incorrect!

lenzsux doesn't even know why his answer is wrong 😂

That's another example why this warning is needed: Beware of lenzrulz. He is the most notorious liar, spammer and hypocrite on EveryCircuit. lenzrulz projects himself as victim, while he's creating resentments by his very own actions, and has been doing so for years. Be wary when he presents himself as tech-savvy individual - his incompetence in the field of electronics is striking. But don't take my word for it, see for yourself. Should you engage into debate with him, keep a hardcopy or screenshots of what was said - he may manipulate his comments. He continuously reposts his crappy spam under the pretext of "cleansing of defamatory comments", but has been observed doing so with crap which didn't even contain a single comment at all. As self-declared master of debates (rather, master of hot air and moronic "Lol"s) he doesn't hesitate to fabricate fake "evidence" to support his lies. He is not interested in Electronics, but in provocation.

Anyway, now that this lenznoise has ebbed off, let me ask sumanth33 again: And what happens to output when one or both inputs are 0?

More fallacious “copy/paste” narratives, why am I not surprised?
lenzrulz

And you’re still toying with @sumanth33...move on already!
Bushmills

I'll tell him why - if his answer is "it'll be 0" - it isn't, but I'm confident that he will notice himself why it isn't 0. Contrary to lenzsux, who is incompetent and cannot think of the reason.

Does “BOTH transistors MUST BE SATURATED “ON” for an output at Q” mean anything to you?
Bushmills
6 years ago
Of course - but that's not an answer to "And what happens to output when one or both inputs are 0?". But please go on and demonstrate your incompetence.
lenzrulz

NOTHING HAPPENS because BOTH transistors MUST BE SATURATED “ON” for an output at Q. Now stop toying with @sumanth33 and move on...😡
Bushmills

Do you know the difference between "nothing happens" and "0"?
lenzrulz
6 years ago
Clearly you don’t!
Bushmills
6 years ago
I do, you don"t seem to, having now answered the same question once with "if inputs A and B are both at logic 0 then output Q would be 0 ("obviously")" and once with "NOTHING HAPPENS"
Bushmills

Anyway, both are wrong.

Oh yes, you may want to read the truth table for future reference.

lenzsux just thought he could pretend that he knows about electronics again, and got in with a loud mouthed "obviously", which turned out to be a foot-in-his-mouth case again. Now he's showing his typical reaction: trying to hide his embarrassing statements behind hot air.
lenzrulz

Nope, just encouraging you to familiarise yourself with the truth table, stop toying with @sumanth33 and move along!

lenzsux still doesn't know why his answers are wrong. Why don't you do a bit more of "tidying up", or maybe stick your head into your toilet bowl, and return when sumanth33 found the right answer. Or don't return, even better.

You're looking at truth table of an AND gate - you don't look at truth table of sumanth33's circuit. And you fail to consider that those differ from each other in an important detail.

@bushmills lenzrulz does not understand any electronics at all. None..zilch.

Lenzrulz is multiple personality, he tries to take different personality with each fake account. Sick phsyco.
Bushmills

I'm quite aware of his utter lack of competence. But it's sometimes hilarious how hard he tries to convince himself of the contrary. Without being spoon fed he's completely lost.
Bushmills

My guess is that next he comes up with some blabbering like "you have no evidence for that I said what I said" or the like.

Are you lot actually out of play school yet? Because of your childish argument we have not got a conclusion to this post, the way l see it is if you had lens on one input and bushmill, Kiani, giomix, on the other input and you turn both inputs on, at the output you would get a load of crap!!!!!
lenzrulz

That’s true, I find myself being needlessly drawn in, but you made a valid point.
Bushmills
6 years ago
Nobody invited incompetent lenzsux here - if he feels "drawn in", it's because of his desire for conflict. Go play with your own crap, don't try to manipulate users with your wrong answers to questions which weren't even directed to you. I asked a sumanth33 a question, then lenzsux filled this comment thread with his drivel.

The output only sources, it doesn't sink?
Bushmills
6 years ago
That's right, rich1129200. When not "1", output behaves as high impedance, "Z" state output, never becoming anything like "0". Though I wanted sumanth33 to discover that by himself.
Bushmills
6 years ago
Means also, it can't pull inputs of other gates to "0". CMOS inputs remain undefined, TTL inputs remain "1"
kiani

Fake accounts of lenzrulz don't understand electronics either..
Bushmills

I wonder why lenzsux hasn't returned, twisting and wriggeling in an attempt to convince himself that he had it right all the way from the begin.

Your play on words is noted and your avoidance in simplifying this circuits functionality is clearly evident as you consistently toyed with @sumanth33. Your “response” was dragged out of you as you increasingly look stupid!
Tedski

The reason sumanth33 probably didn't answer you lot is because he probably doesn't want to converse with a load of kiddiwinks...ha.!!!

lenzsux, "“response” was dragged out of you as you increasingly look stupid!" Your responses weren't "dragged out" - you volunteered incorrect answers twice without having been asked for. Very embarrassing for you, trying to mimic competence but utterly failing to understand even the simplest circuit.

But still no evidence huh?

When lenzsux runs out of arguments, he asks for evidence, ignoring that what he asks for is right in front of his nose.
