A-Z of Electronics – Capacitors

a_to_z_electronics

[Jeri Ellsworth] recently released another video in her “A-Z of Electronics” series – this time Capacitors are the subject. As a penance for my boneheaded AC Capacitor suggestion yesterday (I swear it was lack of sleep talking), [Caleb] suggested that I be the one to write this article. Since I’m not an electrical engineer (I majored in Comp Sci), I enjoy watching these videos, and I share them with individuals who are new to electronics. [Jeri] always presents the subject matter in a clear and concise manner, so the subjects do not seem daunting or intimidating.

She briefly discusses the early development of capacitors, including Leyden Jars, then focuses on modern capacitors and their usage. She covers wiring capacitors in circuits, demonstrating the difference between series and parallel configurations, as well as how electrode distance affects capacitance.

If you have a spare minute, be sure to check out her current video as well as those she has previously released.

    this girl is on a mission <3, I hope technology teachers are using these videos in schools..

    That is one talented person.

    Always entertaining, always informative.

    Had to laugh over the poor birds. :D

    After reading your post i went and watched her other videos and they are pretty good, thank you for bringing this to my attention

    i wish we had Jeri’s videos when i was in school. Bill Nye isn’t really that informative.
    Her videos could make good replacement material for the dumbshit they make kids watch in college nowadays too.. but i think if i would have seen all this growing up, before i ate all those lead pellets and paint chips, the world would have seen some technological advances, we might all be engulfed in a free sea of wiFi, where people can use their skype phones, messengers, etc. freely, until THE MAN steps in, that is..

    As non-electronic person just following it for the pretty pictures and Youtube videos, I must say that those videos are pretty helpful (even started to try making my own fan-controller).

    Fan controller?

    I’m still trying to tape a picture of Voltaire to this Popsicle stick!

    Hahaha, nicely done and quite entertaining. It’s talent indeed. I hope they make some more videos so I can enjoy life better!

    All of Jeri’s videos are excellent. She makes learning electronics, and other things, fun and interesting. Always inspiring. Cheers Jeri!

    Your lack of sleep is forgiven.

    On another note, I’ve subscribed to these vids. I’m new to the electronics world, and these are a great supplement.

    We already knew how to use them. Now we know what they do :)
    Next up… the Diode? Then Eddy currents or E.M. ?

  11. jeditalian says:

    she already taught us how to make the point-contact transistor.. i think diodes were explained there, but if there were a JeriVid for every individual component, i would watch them and hopefully achieve 1% of her genius.

    Cool videos. I thought I recognized her from somewhere – Ben Heck is competing with her on making pinball machines. Apparently she’s going to be on the next episode of his web show.

    @Ben S.:

    Speaking of capacitors I’ve been wondering if it is worth it to harvest the capacitor out of old TV’s or if they are just too big to be of use for anything.

  15. ewruirew says:

    I’m sorry, but I’m not impressed with this video.

    Though the historical part of the video was cutsey and everything, the actual practical electronics parts are rushed through WAY too fast.

    It’s like she’s reading out of a textbook and wants to get through the chapter on capacitors as soon as she possibly can.

    Though informative, you could have probably gotten the same information from a Wikipedia article.

    This is not a very good method of teaching.
