So much better explained than my lecturers at college - where were you when I needed you 24 years ago when I did my C&G 2240 Electronics Servicing course?!
I found teaching beginners, when introducing a new subject, shorter lesson time worked better, maybe a theory lesson then lunch break the practical lesson and Diana hand skills, schematic and multimeter skills are getting better and better, good work.
Can somebody explain to me please if I understood this correctly: 1:09:55 you have to add a 10k resistor before the variable resistor because if you have 12V on the base and 12V on the collector the transistor will get burned. 10k is randomly chosen, it is just a resistor needed to lower the current if the variable resistor is set to 0Ohms (acting like a switch). If there would be no 10k resistor the current would be unlimited and would/could damage the transistor.
amazing! cant wait to we get to big lvl in like 2 3 months :) this is so good! Diana dont allow to teacher scare you :) he love to be scary but he love you so much to he will push all the limits to make you good electrician :)
I have a question: What is the point of building the circuit as shown in the video? Why do you need a transistor for this? I always thought the base would be connected to a microchip or anything, that switches the circuit on demand. But in the video, it turns on as soon as power is applied, so why not just connect it without transistor?
This all takes me back to my youth, thinking it was wonderful to vary the brightness of a bulb with a variable resistor and transistor, at least you learn the basics that you need to find the faults. Fet's and Mosfets in the next video?
Might help if there are more analogies for someone who is a beginner. Like water pressure, flow, etc. how I learned as a hobbiest, until doing more research into the actual production of these components. But she’s right, not her fault, it’s sorins, if she doesn’t understand lol
I don't think you are finished with capacitors. You should wire up an electrolytic capacitor backwards, apply 12V and see what happens. Diana will remember that and always check the polarity of capacitors in future ;-) Also you should have gone into more details about high voltage capacitors and how to correctly discharge them because for example 400V capacitors in a switch-mode power supply can give a very serious electrical shock if they are not properly discharged first.
The patience you have in unbeleavable !!!
I would have thrown in the towel
Thanks Sorin and Diana this series is awesome
Thank you Sorin and Diana. It's really really perfect for beginners and good reminders if necessary for others. 👌
you are such a good teacher...your patience hooked me
I love Diana's "Oh Boy" moments... :D
It seem that its abdead end hahaha cute…

best. teacher and student. teacher get angry. its like school. very interesnteing.and very best vedio
1:08:01 - “Wheeee!” That’s funny, right there!

Great video 👍
very helpful. thanks for this video.
That's the spirit Diana
Poor Diana. She is in intensive learning of a master. Some need months to learn all this.

Diana like to understand things in her way
❤For Diana
Diana is brave lady, Sorin be gentle please
If u didn’t learn something don’t wast our time

OMG, was verry funy !😂
She is learning fast my wife is starting also understand a little
Diana with a t-shirt that states "That is an interesting question".
Dianas 1st circuit. Congratulations. Soon she will be better than Sorin 😁☺☺
🎉🎉🎉

He hasnt talk about capacitors yet
He did, in the previous episode. @@regresoderambo
very interesting
U are amazing
Dayana's word oh shit😅
Next lesson "hadron collider" using transistors 😂, I just joking, thank you 👍

Hello🤝👍👍👍👍👍👏👏👏👏👋👋👋👋👋👏
your wife is already a professionell solderer.
creat ,mouse trap electric pir motion high voltge
You should be proud you have lady like that,my missis only blame me like most of the females just counting money income
