Not everyone in the education field is an educator. Just because someone is brilliant doesn't mean they can relate their knowledge to someone else. It's very much the same in coaching sports. The star quarter-back may have had an incredible career on the field but that doesn't mean there is any coaching potential there. Knowing something and knowing how to convey that knowledge to someone else are two very different things and possession of one is not an indicator of possessing the other.

One _major_ reason why this guy is so good at teaching things is because he gives _several_ example problems. A lot of teachers are content with just showing one example and then they move on to something else, and that always annoyed me a lot, so it's great that these videos show a large number of examples.

He doesn't have to be a genius to do this though. He doesn't even have to be brilliant. He just learns it and teaches it after. Probably even forgets what it's about when a series is over. It's not hard at all. For all anyone knows he's looking at already written out and explained examples by someone else he got to do it for him or something. Surely you don't really believe that he knows everything he's teaching.

I liked especially the problem with diodes in parallel to highlight the concept that the germanium diode with the lower voltage threshold will be the one through which all the current flows! Also the example with the parallel diodes where the one with the greater voltage difference shows which diode will be the one through which current flows.

@dtm7743 4 жыл бұрын

Because since point C is taken as a ground node i mean a reference node all our potentials are measured with respect to it and a silicon diode has a typical voltage drop across it of 0.7 volts one of the terminals is at 0 volts that is the ground terminal so the other has to be at +0.7 volts

@@AI-kr7mj what else node would you take as ground? when talking about voltage in circuit theory the node's voltage has to be measured with respect to a reference node because there is no such a term "voltage" instead we say potential difference the well-known reference point in circuit theory is the ground what is a a potential of 0 so you are not required to take your reference as the ground you can take it else where but i suggest you do not over complicate it you just take the bottom node as ground and all other node voltages will be measured with respect to it

@leroycasterline1122 3 жыл бұрын

At 5:10, you state that the Si diode is off because 'the Ge diode needs less energy to activate.' But it seems to me the reason must be that the forward voltage across the Si diode is only 0.3 volts (as the Ge diode has pulled it up), thus it can't turn/remain on.

@SNoCappidona 3 жыл бұрын

Yea, i am wondering whats going on in that circuit. 2 ideal voltages sources in parallel have the same voltage; these are diodes so i guess that doesn't apply. If it is true that only the Ge diode turns on, then i suspect there is no real practical application of this circuit and the silicon diode is redundant.
