Hi professor, I am from India. I am not yet in college but am taking Electronics and Telecommunication Engineering. Do I start with this playlist or the circuits one and what are the pre requisites for these courses? Oh I just saw your reply over a similar question. Thank you
Thank you for posting these Professor Holman. I’m currently enrolled in this class online for a different institution and I don’t do well with the online lectures at my disposal there. I’m going to dive into these head first as I come up on the last half of the semester.
If an ideal diode has VD > 0, then it cannot be turned off with ID = 0. On the other hand, if an ideal diode has VD < 0, then it cannot be turned on with ID > 0. That is the contradiction. If an ideal diode is off, then VD < 0 and ID = 0. If it is on, then VD = 0 and ID > 0. I recommend that you watch the next lecture with additional examples of ideal diode circuits.
Hi Professor , I still didn't enter the college and I want to study EE , would this list of lectures help me to study a little bit before I start ? and what level are these ? thank you so much
Before watching my Electronics lectures, I recommend that you first watch my Circuits lectures. You'll also need some background in physics, linear algebra, and calculus to understand some of the concepts introduced in both courses. As an EE, you'll be required to take the following core courses during your first through third years at a university: (1) Physics (in particular, the fundamentals of electricity and electromagnetism) (2) Mathematics (linear algebra, first-year calculus, differential equations) (3) Circuits I (DC and AC linear circuits, nodal analysis, mesh analysis, op amps, phasors, etc.) (4) Circuits II (frequency-dependent circuits, filters, Laplace transforms, etc.) (5) Electronics I (transistors, diodes, amplifiers, small-signal analysis) (6) Digital systems (Boolean math, combinational digital logic, state machines, computer organization) (7) Programming (using structured languages such as Python, C, or Java) My RU-vid lectures cover (3) and (5), provided you have sufficient background in (1) and (2). You can check out Khan Academy for those. Watch (3) first, then (5). Good luck!
@@wtimothyholman yes Prof , I did study (1) (2) and finished few weeks ago I can say I am pretty good at Mathematics and good at the basics of Electricity , Circuits , diodes , logical gates , resistors , both DC and AC circuits and RLC circuit , and I do fix some simple PCBs from time to time , thank you so much for your advice , and Good luck for you 😇
(1) Sedra & Smith "Microelectronic Circuits" is used by a lot of universities for introductory courses in electronics. It's not perfect, but I think it does a good job overall. I have used it for many years. (2) Franco, "Design with Operational Amplifiers and Analog Integrated Circuits" is an excellent textbook on advanced analog circuits using op amps. (3) Allen & Holberg, "CMOS Analog Circuit Design". This is a classic textbook on CMOS analog circuits. (4) Razavi, "Design of Analog CMOS Integrated Circuits", another excellent textbook on CMOS analog design. I think that he is still updating the textbook and putting out new editions. (5) Horowitz & Hill, "The Art of Electronics". This is arguably one of the best-known desk references for electronic design ever written. Every working EE should have a copy, in my opinion. (6) Gray & Meyer, "Analysis and Design of Analog Integrated Circuits". This is an older text that focused on BJT circuits, but is an excellent reference on basic analog design principles. (7) Baker, "CMOS Circuit Design, Layout, and Simulation". This textbook is almost like an encyclopedia of CMOS analog and digital circuit design. (8) "The ARRL Handbook for Radio Communications", any recent edition (updated yearly). This is not a college textbook, but it has one of the best sections on practical electronic circuit design and construction that you can find. There are many other examples, but I think these books will give you a good starting point.
No, a hole is created when an electron gains enough energy to break free from an atom, resulting in a net positive charge in the orbital shell due to the missing electron. So the way to think about a hole is that it is not a positive particle like a proton, but instead a place where an electron has been removed. However, in semiconductor physics it is convenient to treat the hole as if it was a positive particle, because it makes the equations easier to work with.
@@wtimothyholmanEnjoyed your presentation I have a question about the current flow thru a diode as you presented I look at electron flow thru the diode as electron current flows against the arrow in forward bias Can you help? Just subscribed CHEERS
@@anthonysova7117, in standard circuit analysis, positive current is defined as moving in the direction of positive charge. Since electrons are negatively charged, then positive current moves in the opposite direction of electron flow. It seems counterintuitive today, but the scientific world had adopted the convention of "movement of positive charge equals positive current" long before electrons (with negative charge) were discovered in the late 19th century. The world was using electricity decades before the modern theory of the atom was developed.
