Trace the path of current flow from a transformer through a bridge rectifier for positive and negative cycles. Paper scan: agnd.net/youtube/2019-10-14_r...
Hey, I've got a question. Wouldn't there be current flowing in both directions through the GND to GND connection (GND between the secondary coils and GND between two resistors) at the same time? Thanks
In concept, yes. In reality, no. The actual current flowing, that you would measure with a meter, is the summation of the current in the two directions. IF there is perfect symmetry, then these are equal and opposite. In that case you could cut the GND-GND wire and there would be no effect on the situation. Real circuits never have that perfect symmetry, so there would be a small net current in that wire. The difference is the same as a 3-phase power system with 3 or 4 wires -- a (perfectly) balanced system with no harmonics has zero current in the 4th wire, "neutral".
Honest opinion here: Too much drawing and explanation and "side bar" explanations of other things and the different colors of pens as well as drawing backward arrows to explain negative electrons was way too complicated. You took a fairly easy circuit to explain and because I believe you tried to hard made it almost frustrating to watch. That Sir is unfortunately my opinion and had to watch only 1 other video on youtube to understand the circuit. And no...I could not do better or I would not be searching for "how a rectifier works". Look at the bright side and anyone that wants to critique me: youtube even credits the creator for poor comments...as long as a site gets comments you get credit, good or bad.
Agree with comment - this was far too complicated of an explanation. Another channel that does a better job is - th-cam.com/video/EkHch86UXpY/w-d-xo.html. Just Sayin.
Dan, your the FIRST one to explain the current flow via the schematic and through the GND. THANK YOU!
Thanks for the thanks and glad you found it helpful!
this video is under-appreciated, thank you dan white!
Gandalf diode made my day :D. Great video, thanks a lot!
Thankyouuuum you are the only person to ake video on this topic.

@@DanWhiteValpo Thank you for answering. That helped quite a bit.
May I know the purpose of R1 R2? Thx
