Current flows from negative post of battery to positive post. In a Forward biased diode, current flows against the arrow. You're backward in your theory.

@Peter_1986 4 года назад

My Electronics course uses the book "Microelectronic Circuits" by Sedra & Smith. I am not really a fan of that book, since I find it dry and long-winded. I tend to prefer "Fundamentals Of Microelectronics" by Razavi - it's not QUITE the same content, but it's very similar, and includes typical topics such as diodes, transistors, small-signal models, rectifier circuits, and so on. It doesn't include zener diodes though, but it has a teaching style that I definitely prefer over Sedra & Smith. And also, Razavi himself has tons of videos on several Electronics courses, and has a pedagogical style much like The Organic Chemistry Tutor.

Althouh Zener Diodes are a bit old-school, they do have some modern applications. Back in the 80's, I worked on the first Transatlantic Fiber Optic Cable (TAT-8). It had repeaters every 25 Kilometers or so. The power for all the repeaters was several thousand Volts with each repeater having a Zener of the Voltage needed to power the Repeater in series with the Power. Think of it as a High Voltage supply with a string of Zeners in series with the output, each repeater having it's own Zener with the voltage and current being taken off across each Zener. Quite a simple setup, but it worked quite well.

Good video on the zener diode Given the high voltage noted in the DC 50V example, you should have spent a moment to discuss P=I*V and the importance of the power ratings of the resistors. Some novice viewers might replicate this circuit on a breadboard using an improper 1/4W (.250) resistor and be alarmed by the magic smoke.

I always see comments like this. And I always think.. then you've seen it once before then if you mention school. If you (someone) went to college with out any knowledge of the subject beforehand of course it will seem like they didn't teach it to you. Not that there aren't bad jobs done at colleges etc, but don't discount that you have to familiarize yourself with subjects before you can try to understand them.

@duanethompson2360 4 года назад

I was hoping you would cover voltage shifting with the zenier in series in the secondary of transformer to drop its voltage by the zenier value. I work with Tube amps a lot and the mains used to be 110ac, now there 120+. I was thinking of adding a 10v zenier in each leg of a center tapped secondary to drop the high voltage.

@goldenfairyautomobiles2325 3 года назад

Good, if the out put is connected to a transistor base pin with proper connection then it will become a voltage regulator transistor, and also zener diodes were used for starting of electronic devices by feather touch switches.,pre determined settings for any comparator's also zener diodes were used, and zener diodes were regulating the complete globe in smps power supply put.

I made my own 2 amp regulator using a zener , saved buying a to3 cased lm 780x device, just have to stick to a fixed input and output voltage so not to over current the zener.
