CircuitBread is all about electronics and electrical engineering tutorials, with content on how electronics work and some extras for fun!
There are many topics that we want to get through and while we’re planning on starting with basic electronics and microcontrollers, we have plans for a wide range of practical and theoretical videos on AC and DC circuits, microelectronics, electronic devices, semiconductor devices, communications systems, robotics, control systems, digital logic, electromagnetic theory, and… well, probably more, but that’s quite the list as it is. Mixed in with tutorials, we want more lighthearted stuff - tradeshows, faires, spotlights on people and companies, parodies, etc.
This content will appeal to anyone with an interest in electronics and electrical engineering and, while passionate, doesn’t take themselves (or us!) too seriously.
So, subscribe and follow us on this adventure as we learn more about electronics together and have a little fun while doing it!
Well, as a retired Electrical Design Engineer, I must say, this video may be embarrassing! You said that this is in your shed. If it is, where is the Required disconnect? No main breaker as the required disconnecting means. Got one outside? There is no GEC in the panel. Where is your required Grounding Electrode and conductor connected? “This is a 2 pole breaker, that’s what I think it’s called”. Very embarrassing comment.
As @sureshchattu5211 mentioned in another comment, I believe you have the two region names confused at 2:11 and 2:34. From my understanding the area before VGS equals the threshold voltage is the Ohmic region. The region past the threshold voltage when the MOSFET is fully conducting is the Saturation region. If I'm wrong please let me know! Otherwise this was a fantastic video!
Thanks! We actually did another video that addresses this specifically: www.circuitbread.com/tutorials/what-are-the-different-regions-of-operation-for-a-fet I think, in this case, the biggest challenge is that, in this video, we are showing what happens when you increase VGS. Yet almost all graphs that show this curve, including ones we've made, have VDS as the x-axis. So, to help see why we *think* we are right (hey, I'm not going to claim perfection - ever) look at one of those graphs and then, instead of moving left to right, choose a VDS voltage and then look at the regions you move through as you go from the bottom to the top. It'll be cutoff, saturation, then ohmic (or linear). Hopefully between that quick explanation and the other video, this will be clear. RU-vid is not great about notifying us of responses to comments but I would love to hear if that cleared things up!
@@CircuitBread thanks for the reply! This makes total sense and I agree, the terminology is incredibly confusing! Your linked article does a wonderful job of further explaining these regions, thanks!
12 BITS WORDLENGHTS... 1001 MAY BE WRITTEN AS 0011,0101,....IF > 1 THRESHOLD V. SO THICKER THE DIELECTRIC SO THAT 1 CELL CAN HOLD THE THE CHARGE LEVEL OF 12 BITS WORDS...?🤔
Hey I think this may answer a question Im trying to figure out. What is the main difference between a hobby grade ESC & the motor controller/receiver board of a toy grade RC car. It seems the toy grade board has no PWM & the hobby ESC does. Both of the have H Bridge is this a correct guess? Since speed isnt controlled by the TX this means the toy RC has no PWM?
@@CircuitBread Current flow (electrons) flows from negative to positive. Always! That is what I was taught by the US Military and that is what I have been using for over 40 years.
Point of correction. The 240v is technically not out of phase. They are 180 degrees apart not 90 degrees. If they were out of phase you would have 208 v because you would have a three phase supply. You have the common 240v split phase service.
