    Just started to be able to quantify this type of circuit.. awesome to see it in action!

    at resonance Xc=Xl
    solving for resonant frequency we have:
    Xc=Xl; substitute formula for xc, xl
    1/(2*pi*f*C) = 2*pi*f*L
    we got:
    f^2=1(4*pi^2*L*C); taking the square root of both sides we have:
    fr=1/(2*pi*L*C)^1/2

    ok,a SERIES RESONANT CIRCUIT makes the most current at resonance, resonance happens when the inductor and capacitor are in a perfect phase between induction and capacitance, its like filling one cup and then filling the other efficiently. a PARALLEL RESONANCE CIRUIT, like teslas work, allows the reduction of current to almost zero(possibly zero at really high voltage)with the same phasing of induction to capacitance and allows really efficient power conversion when applied for human consumption

    @LokiClock The existing oscillation is coming from the circuit: AC powered RLC circuit. The switches change the capacitance of the circuit (presumably).

  • @salmif61
    @salmif61 Год назад +1

    The totale impedance is equal to sqrt(R^2+(Xl-Xc)^2) and at resonance frequency XL=Xc so totale impedance at resonance frequency is the minimum impedance wich is R so at resonance frequency current current is maximum

    Old school tech, very well done! The bulb is brightest at the resonant frequency.

  • @paultarshipspeckerwood956
    @paultarshipspeckerwood956 8 лет назад +9

    Resonance is where, inductance continually gives it self to capacitance, and visa versa, it is essentially forming a 90 degree corner, with the speed of light, hence squaring it, through space emptying the magnitomotive force, which charges the counterspace around the die-electric. And apparently there is no public knowledge about the speeds of the die electric, and magnetic feild lines, that is, individually, if that is possible. watch all the videos on the website Eric P Dollard.

  • @lazzer408
    @lazzer408 15 лет назад +8

    Why don't you just reroute power from the warp core through the plasma conduits and direct a subspace tacheon pulse using the main deflector? That would be much more effective at lighting a bulb.

    I propose an abstract concept: how about we upvote the best explanation of this.
    The video response is pretty good. I bet it could be done in 3-5 sentences.

  • @Guitare_picking
    @Guitare_picking 11 лет назад +2

    you have to calculate Z(jw)
    the circuit will be resonant when Im(Z) = 0
    don't forget to take into account the Q factor, and eventully the resitence of your source.
    Maybe the easiest one to do is the RLC serie.
    in the case of RLC serie resoance will happend when : w = 1/(L*C)^1/2
    if you'r doing another set up (random)you have to caculate w in each case.
    My englsih is not very good sorry.

    I'm glad you have a system that works for you in the UK. The same system would absolutely fail here in the US. Our government is barely capable of managing our social security system let alone something as complex as healthcare.
    You're right though - this doesn't belong here - the free energy idiots just get me worked up to no end.

  • @boxa888
    @boxa888 16 лет назад

    the circuits will look different and also function differently,teslas work is alot more special and beyond these basic resonant circuits and he truely was a discover in series and parallel resonant circuits.he was also able to take what he learned and apply it to a earth power and internet system 100 years ago, his first tower was wardenclyffe, and his reseach was at colorado springs.here he created special circuits that allowed energy to be tapped anywhere on earth from a centralized station.

  • @FlavoredCoffeeGuy
    @FlavoredCoffeeGuy 16 лет назад

    You spell less in all capitals, and it's in the middle of a sentence.
    The light bulb sees the same amount of power for the same brightness. The primary sees the same amount of power as the secondary. But, mutual inductance causes the inductive reactance of the primary to change, and the resonant frequency. The slug tuned circuit shows that in order for the resonant frq to be the same an adjustment must be made. Resonance of a capaictor & coil in parallel is higher than either alone.

  • @JohanZahri
    @JohanZahri 9 лет назад +2

    If the light bulb is replaced with your ordinary resistor, will the circuit work?
    Will it create a humming/hissing sound when not in tune?

    nikola tesla!! yeaaa! theres more importance to this circuit than people realized. really its the parallel resonance circuit thats important for a world wide energy transfer system and a one wire transmission system created by tesla, which disproves a closed system principle. i put up information on it or just search nikola tesla wireless power.

  • @hellomate639
    @hellomate639 15 лет назад

    We learn about this stuff in high school too. It's just that people review physics here so that they are better professionals and more prepared for grad school.
    I encourage you to come here for college because the American University system is the most reputable in the world.

  • @FlavoredCoffeeGuy
    @FlavoredCoffeeGuy 15 лет назад

    XL = 2*pi*f
    XC = 1/(2*pi*f)
    In all of that, you still haven't figured out that the light bulb still uses the same amount of energy for the same amount of brightness. When XL and XC are equal and in parallel and f is the impedance of the the two is higher than either one. The bulb never uses less energy. But, the higher f, the higher the effeciency, the primary will use less, and the bulb will use just as much. A transfomer only operates around inductance, that includes reflected impedance

    Inductance, mutual inductance, reflected impedance, resonance, do the math. I am 100% certain that standing next to the river, cannot measure by looking how wide it truly is. Likewise you cannot determin how deep. So, to say that there is no way a 100,000 gallons of water could be rushing past any given point of it. But, if I did the math, measurements, and I knew, you kept acting like there's now way. That is exactly where you are.

    I have a degree in physics from cal poly. What is your education? For example, I know that the words "year", "college", "electronics" and "earth" aren't capitalized. That's because I, unlike you, have an education.
    Trying to disprove the law of conservation of energy is like trying to disprove gravity. And besides which, if you knew even the slightest bit about electrical theory, you'd know that the bulb actually sees LESS current overall than if it were connected directly to the wall.

    So, is anyone going to actually measure how much power is coming from the wall and compare it to how much is passing through the bulb. That massive iron slug makes resonance impractical but, you've got to recognize an over unity device when you see one. If Q=50 1/50th of the power is being drawn from the wall, and 50 times that is passing through the bulb. MIT Dummies.

    • @ClergetMusic
      @ClergetMusic 3 года назад

      The idea is that when the circuit is in tune, it will generate the greatest output. When the light bulb is the brightest, the circuit is “in tune” and the capacitance and inductance are at their optimal balance. The iron core controls the inductance of the inductor, and the switches attached to the capacitors add and subtract capacitors from the circuit to change the overall capacitance. When they’re balanced, the bulb is at its brightest, and when they are out of balance, the bulb dims.

  • @FlavoredCoffeeGuy

    Not enough room in the 500 words granted to text box to make any sense. It is simple, if you have a Degree in Physics, you are not doing the math concerning inductors, parallel resonant circuits, transformers, and you're not doing any labs, and maybe your degree is a minor and you can calculate how far you can throw something. But, fact remains you don't know the physics of this circuit, nor understand it.
