Different ways to connect transistors

141

01:12:54

There are many different ways to connect transistors with different loads. I don't think that any of those is wrong, it just depends on the application. (Experts, please correct me if I am wrong)
It matters where you connect the load, in this case a LED, because different configuration will require a different voltage source and as you may notice from the examples will provide a different current in the circuit. 
In my tests the LED had to have the current flow around 20mA, and where the current was exceeding a lot the 20mA I have set up a solution with a resistor connected to base of transistor (in a separate circuit close to the original one).
I hope that this will help to learn more about the transistors.

Good job !!!

yes, different they are, but most of them are not very common. I dont like them. I hope you can do better You propably know there is common emitter, common collector and common base. This is possible for NPN as for PNP. Makes six different circuits.

How about publishing a corrective circuit rather than mouthing off condescendingly?

Hurz, I heard about common ones and actually I just learned about them in a course. It didn't make much sense until you pointed it out too. Thank you very much. Will need to do some more experiments though in order to learn the basics.

Lenzrulz, I don't understand what is your problem here but I hope you are having a good day.

@Kardier, I don’t have a problem with 99% of the EC community, but creepy circuit stalkers, cowards using script to post unsolicited messages onto multiple users accounts and cyber bullies are problematic. I’m have a great day and I hope you are too...👍

@lenzrulz, I use this tool to learn and experiment and hoping that someone will point out to my mistakes and help with solutions or maybe learn together with me. It is part of my learning process. If you don't like it please just ignore. I suppose that you are not a moderator here or whatever you pretend to be by dictating your rules, so please don't spam if you don't have anything related to the circuits to say.

I definitely don’t “spam” but there are other users who love spamming circuits of users they disagree with.I Ali agree that ignoring circuits we disagree with is the best solution. Finally, I have no rules to dictate unlike EC’s notorious cyber bully.

@lenski, define the word "spam" LOL. Lenny you are a spammer. Go home and let us do electronics. You are not interessted in. Stop your spam you are a spammer. And yes, you have with more then 1% (must be hubdreds tontousends) of this community users a big issue. Stop dictating your philosopy of spam taktic and shutup or come with valid electronic. common emitter common collector and common basis and this please for NPN and PNP thanks Troll

@Kardier, as Lenny has nothing valid to present, but spam and terror. I prepared a little collection based on Everycurcuit BJTs as i was talking about. I hope you dont get the impression all EC users are idiots. Check this if you have question http://everycircuit.com/circuit/4562709386100736

All empty rhetoric fuelled by lies because he’s been comprehensively beaten on so many occasions that he now resorts to a cowardly habit of hiding behind a script, and he still isn’t winning...lol

Thanks @hurz, I will take a look.

@lenski, everycircuit is not a combat game, nobody is beaten. Even one would you are incomoetent to see and understand, lol. Show me one ly out of so many you said. You are here since 6 years for terror.

@lenzrulz, I have a question for you, not related to the discussion you have about the circuit in subject though, how old are you?
