    I'm taking a $150.00 Udemy course, and the teacher just blazed through this, gave a single example, but explained it horribly and just moved on. I still had no idea how to actually use the formula or exactly what we were solving. I spent the last 45 minutes trying to use what he taught me to no avail. After just 6 minutes of watching your video, I understand it completely. You have earned a sub and I will be coming here to supplement the Udemy course. THANK YOU!!!!! You're a very good, straight forward teacher.
    Edit: Oh, wow. You went above and beyond. He didn't even attempt to teach us all of the other stuff, like finding the number of time constants to get to a certain percentage.. I'm not a math guy, so you really have saved me here. Thank you 🙏

      Your comment is so funny that your professor that has a doctorate is a scientist, not a teacher. The university hired him to do research, and if he is a good teacher than that's just a bonus. Students don't seem to know this. People just look to blame other people or circumstances for there failures. Suck it up and do something different to learn the material.

      @@TiberiusStorm Do you know why? Because physics professors are physicists. They assume you want to be a scientist or engineer. So some feel the responsibility to be gatekeepers. They will see if you really have the work ethic to make it. This is especially tough for students who skipped physics in high school. Long story short, I did skip physics in high school for personal reasons but I am now a physics major in my junior year. You want something bad enough you go get it.

    I wish this had been around back in the day when I was in school… and I do mean BACK in the day. Way back when the internet was shared only between research organizations and government agencies, and before the first website went live, I conned my way through the stand-in-line-to-get-a-stamp-on-your-sheet college registration process to get into a couple of courses without having the prerequisites (which I probably could not have done quite so easily in the time of modern electronic records) and had to work hard to keep up, using old textbooks to cover gaps in knowledge. Turns out that is pretty hard to do!
    As it is, in my fifties, still stubborn, and still taking on new challenges, I am truly humbled and grateful that someone would go to the effort to share their gift for teaching and put out content like this.

  • @karielf8947
    @karielf8947 ปีที่แล้ว

    the charge stops because there is no more DDP (capacitor voltage is equal to source voltage), and when the discharge stops also there should no more ddp (capacitor voltage is equal to risistor voltage), but the capacitor voltage at the end is quasi equal to zero! that means that resistor voltage becomes low because of ohm losses?

  • @keypo790

    because im dumb, is it correct to assume that a tau represent a 1 cyle of a wave, a period.... and resistance * capacitone describe a period. and I don't know where that formula came from. and then in this equation it represents a time it completed a cycle correct? thats why its being divided by rc to know the rate it complete it cycle...

    Another method for "How much time does it take for the capacitor to reach 90% charge?"
    Just keep plugging in "e to the power of x" into your calculator (or just the google search bar) with reasonable guesses for the power. You want the result to be 0.1, which is 10% left, because you know that e to the power of (-t/tau) is equal to the percentage you will have LEFT TO GO at any given point. After very minimal trial and error, you get approximately 0.1 for the answer when you plug in "e to the power of -2.3". Now that you have the correct power, you know 2.3 = t/0.5. And thus t=1.15 seconds.

    Discharging a capacitor
    Why should a capacitor discharge? Imagine the capacitor with all its charges is kept inside a bag and tied at two open ends (open-circuit).
    The positive charges on one plate are attracted strongly to the electrons on the other plate, and the electric field is strong and uniform between the opposite charges on the plates. The opposite charges on either plate seem to hold each other tightly. The field is not so strong to cause the electrons to cross the gap and reunite with the positive charges.
    There is a fringe field at both ends ready to burst the bag, but the open circuit does not allow charge flow in the external circuit. The electric fields of surface charges which move onto the wires from both the plates and the fringe field will, during the initial transient when the wires are attached to the plates, combine to make the resultant electric field in the wires, zero. The fringe field is different from the field between the capacitor plates.
    When the charged capacitor is short-circuited using a wire, the effect is to open the tied ends of the bag and the charges are released. The fringe field causes the initial crucial release of charges for further flow of the charges….and development of surface charges that will enable the charges to flow around the wire, and neutralize each other. After all the charges on the plates are neutralized, the circuit attains a state of static equilibrium, a natural relaxed state of equilibrium and we say the capacitor is discharged.
    Electrostatics and circuits belong to one science not two. To learn how a capacitor charges and discharges and the origin and role of the fringe field in the circuit process it is instructive to understand Current, the conduction process and Voltage at the fundamental level as in the following two videos:
    i. th-cam.com/video/TTtt28b1dYo/w-d-xo.html and
    ii. th-cam.com/video/8BQM_xw2Rfo/w-d-xo.html
    It is not possible in this post to discuss in more detail the formation of the fringe field when a capacitor is charged and discharged.
    The last frame References in video #1 lists textbooks 3 and 4 which discuss these topics in more detail using a unified approach and provide an intuitive understanding of discharging a capacitor with the help of sequential diagrams.
    Charging a capacitor
    "The voltage across a capacitor cannot change instantaneously" is a statement one finds often in textbooks on circuit theory which discuss the application of a step voltage to an RC circuit.
    Most students memorise and apply this in circuits without understanding the physical processes involved.
    It will be useful to learn the operation of charging a capacitor using a unified approach to electrostatics and circuits.
    It is not possible in this post to discuss the charging of an uncharged capacitor. During the first few nanoseconds after switch ON, while the surface charges arrange themselves, there is no electric field E_cap and fringe field because there is no initial charge on its plates; it is as though the capacitor was not there - as though there were a continuous wire with no break in it.
    The last frame References in video #1 lists two textbooks 3 and 4 which discuss in detail with a series of diagrams the physical processes in charging a capacitor without and with a resistor (RC circuit).
    It is not possible in this post to discuss in more detail current in capacitor circuits and capacitive reactance. The last frame References in video #1 lists textbook 4 which discusses these topics in more detail using a unified approach and provides an intuitive understanding of reactance.
    Textbook 4 is here techsarworld.com/product-detail/fundamentals-of-electric-theory-and-circuits-559
    It also describes with sequential diagrams how the current leads the voltage across the capacitor by 90 degrees.

      e=2.71828. You can double check on your calculator. Hope that helps.

    How many subscribers do you need to get to finally make your audio better/louder mannnnnnnn? Every time it goes to an ad or to the next video I blow my speakers... Been watching for years and it's still the same. It's one of the easiest things to fix on your own and you don't need to pay anyone to do it, just pull that volume dial up about 8 to10dB before uploading. I'm down about $400 worth in speakers now from blowing so many lol

    BUT when I type in 1-e-1 on my calculator it doesn’t come up with that answer. Can you please explain step by step how to type it in my calculator, maybe using brackets or something.

    • @MegaSuperJelly
      @MegaSuperJelly 5 ปีที่แล้ว +1

      make sure you are putting e to the power of 1 (e^-1) and not just doing -1 on the end there

    • @hamzahaimeur2815
      @hamzahaimeur2815 5 ปีที่แล้ว

      on some calculators you just need to type e-1 and not even the ''^'' because it puts it automatically
