A conventional current is true because the current isn't just flow of electrons. In electrical current, all charged particles move. Including positive. Positively charged particles flow in one direction, negatively charged - in opposite.

@Dr.Pepper001 2 года назад

In 1966 I was a Marine stationed at Camp LeJeune in North Carolina. My Company Commander sent me to a 4 week course on transistors. About 99% of the transceiver equipment in the Corps at that time used tubes. I graduated first in my class and was rewarded by my Commander by a promotion to Corporal. Imagine sitting in a class for 7 hours a day for 4 weeks just learning about transistors. We went into detailed theory and saw movies on the process of manufacturing all forms of transistors; plus we did lots of lab work where we built transistor circuits and learned how to troubleshoot them. I'm 75 now but still remember much of what I learned in that course. After I left the Corps in 1968 I became an Electrical Engineer and worked mostly with communications receivers and sonar until 2012 when I retired. I had a great career and now I mostly goof off on the 5 country acres my wife, 4 cats, and I live on. Cheers to all.

Over 55 years ago (when I was 10) I was given a birthday present of a simple electronics kit. Several things could be made from it... from buzzers to flashing lights, to even a simple SW radio. While I had no idea at the time what was happening (in terms of the Physics), and needed only to follow very clear instructions as to how to wire the components, the fact that "joining all these bits" in different ways resulted in things with very different properties was very exciting. Now - over half a century later - I discover this remarkable video that beautifully explains the inner workings! Excellent material.

The excellent explanation starts at 14:00. Before that it's just visualizations using water pipes and such which does not explain how a transistor works at all.

@zombieregime 3 года назад

Side note about conventional vs electron flow (which im sure is covered in the battery video, but i like explaining it, so here I go...) Imagine a pipe that contains a row of marbles. In order for a marble to move there must be a space for it to move into. To create a space for a marble to move into, ie a hole, you can remove one marble from the end and the rest of the marbles will shift forward one marble space. If you slow this down as you remove one marble from the end the next marble will shift into its position which now opens a space behind it for the next marble shift into, and so on down the line. As the marbles, ie electrons, shift in one direction the wave front of their motion, ie current, moves in the other. Moving electrons give rise to electrical current. Ergo to have current in one direction electron marbles move in the other. Grasping that concept was incredibly helpful to understanding more about how electricity and electronics work. Also this videos visuals of the doped regions of a transistor and how they function are miles above any other explanation I have ever seen. And I'm no spring chicken. Thumbs up.

@georgewashington90 3 года назад

It is first very good explanation of transistor work in necessary details ( the base voltage 0.5V when transistor is still closed and the 0.8V and greater when transistor is opened is important information, transistor does not get opened in range from 0 - 0.5V). Any person who wants to do anything with transistor should watch it.
