      @@TheMagnay it's not just simple math, per say if you make electronics but it has a eprom chip in it and you want your micro controller to process all of the data in that eprom chip, sure you do math like resistors, capacitors, and crystal oscillators so that you don't fry your circuit and so that your circuit works, but it uses things like connecting the dot's, and oh boy does it get complicated, take a look at this video, and you will understand. ruclips.net/video/LnzuMJLZRdU/видео.html and i'm not being biased, programming is pretty difficult to learn, but once you learn it, it get's easy, same with making circuits, but if you learn how to make electronics you basically know how to make anything, you could even control other electronics, and understand how a computer works fully, but without the right program your circuit wouldn't know what to do. both programming and electrical engineering is very difficult. here's a 3d printer i'm making. easyeda.com/Cipher0/3d-printer

  • @chrisgreenman5350
    @chrisgreenman5350 9 лет назад +30

    When I learned all this stuff we used E for voltage (Electromotive force). so E=I*R. Also is worth noting that the triangle works for wattage P. Using E in place of V you get the pie formula. P=I*E. Solving for the other values, I=E/P, and E=P/I.
    Another trick for those not algebra savvy, start with the basic formula E=I*R. the idea is to get the value you DON'T know to be by itself on one side of the =. You do that by dividing both sides of the equation by the value you KNOW.
    So if you know voltage and resistance but not currently you divide both sides by the resistance as follows.
    E/R=(I*R)/R
    NOTE: the ()'s are to show that you must multiply before you divide which is the natural order of precedence in math.
    This is allowed because you're doing the exact same (equal) operations on both sides of the =. Also note that any time you have a number (or variable) over itself (i.e. 2/2 or 5/5) it always equals 1. (think 2 halves make a whole). So to make it easier, the Rs on the right side cancel each other out. (I*1 is just I). To balance the equation again you have to do the same thing (divide by R) to the other side.
    E/R=I*R/R which equals E/R=I. Since bother sides are equal you can flip it back to front and you end up with I=E/R.
    This is how I learned it so it might be more confusing to some or it might help.
    Enjoy.

    I know all about Ohm's Law, I'm an audio engineer by trade. That being said, I always enjoy your videos Bruce. even if I am familiar with the subject matter, I generally always watch your videos. One can never have too many ways of explaining something. The more we are exposed to a concept, the more we become one with the abstract subject matter and the better we are at applying the knowledge we have. Because, even if we know a subject, if we don't know how (or often times when) to apply the subject, we do not truly know the subject.

      Actually what current is measuring is the amount of electrons flowing thru a conductor in Coulombs and being pushed by an Electro Motive Force, EMF, and measured as Voltage "E' , which both are struggling to overcome as Resistance "R", which is the conductor/wire they are flowing thru.

      Yours is the first intelligent remark. I think Ohm's discovery is telling us about a relationship between mechanical work done driving a population of electrons through a conductor and energy used up against friction, meaning that it is converted into heat energy.
      Voltage is also known as 'potential difference' or just 'potential' and is a unit of energy. Ohm' discovery and formula doesn't always take such a simple form as is discussed in this video. There are resistances described as dynamic with a non-linear connection between voltage and current.
      In more advanced work Ohm's Law is superceded by Kirchoff's Laws and Ohm's Law becomes the Expanded Ohm's Law.

    Very practical teaching style. Like the extra analogies to draw back similarities in other fields of life to help understand. Have just started my electrotech apprenticeship in Australia and have a teacher from Mumbai and im, not a racist, just saying the learning curve is big enough without the accent barrier to go along with it. Please do keep making videos :)

    Back in the early eighties I was given the two triangles W over A x V and V over A x R. The phrases we were taught were 'What Are Virgins' and 'Virgins Are Rare', so easy to remember. Now trying to relate it to P and I had me foxed for a while and watching this made it some much clearer. Thanks.

      Actually... it's I because of the French. It stands for intensité (de courant). Not impetus.

It reminded me of the Ohm's law Triangle; that'll definitely save my hyde in terms of memorization. Thanks lots!*

    Great teaching! Massive electronical reminder for me personally. Two things. First, I was LITERALLY laying in wait to kill a fly when you took your pesticidal break. GREAT minds think alike, clearly. Second, right along with each variant example would have been welcome a practical life example illustrating why I would WANT the cofactors in that particular configuration or another. It all cuts to my motivation as a listener. My reason to want to know these things...if that makes any sense. I found myself hairing of into an imaginative flight of fancy where you are the prescient doomsday prepper dropping critical tidbits of live or die survival info to a currently, relatively lackadaisical public at large. I have a good imagination, I know. Either way the price was right, and I'm grateful as always to find amazin' content on RUclips. Many Thanks!
