The representation of voltage by "height" and current by "pressure" is so easy to understand and imagine. These animations are really helpful!

[@JC-XL]

Absolutely. It makes the operation of the circuit very easy to understand. Maybe because I'm a water/hydraulics engineer and there are analogies between hydraulics and electronics but this makes it immediately clear.

[@billygo6135]

rahu1994 some others, Louis Rossmann explains voltage as velocity of let say, a car, and amperage as its weight, compared to a running human individual when hitting an object at same velocity, the impact of the car having more weight will cause more damage. But voltage and amperage are proporcional in most cases, I only know static as the only exception where amperage is low and voltage very high....

[@ludiProjects]

A good analogy for me is that voltage is pressure, current is velocity.

[@ThatEEguy2818]

Voltage is pressure. Current is flow rate at any given instant. The speed of the flow is always the same.

i got a boost converter, seems like magic now it seems so simple.

[@chrisw1462]

Need a small correction: "The current through this inductor will keep increasing..." No, it won't. Even if it was a perfect inductance, the battery (or whatever voltage source) has internal resistance that would limit the current or cause it to fail. In reality, the internal resistance of the inductor would limit the current eventually, but more likely would cause the inductor to heat up to the point it fails long before that.

[@feynstein1004]

Hey Eugene, do you think you could make a video on an idea of mine? It's quite simple, really. Just wanted to know what would happen if you make a spherical object rotate faster and faster? Assuming, of course that the material is strong enough to withstand being torn apart by centrifugal forces. I think that the sphere will ultimately flatten out into a disc but I'd like to hear your opinion on it. And great video as always.

[@pendalink]

I can tell you're not looking for someone to reply, but maybe I can still provide something of worth. The sphere you speak of would indeed experience outward forces due to its high constant radial acceleration at any radial velocity; the closer vertically to its equator, the greater an outward force would be felt, and its material would want to follow Newton's 1st law and expand move outward. What happens at high speeds depends on the internal forces. If the sphere has high molecular bond strength it may resist deformation to a point and then explode, or stretch out to a maximum and then tear apart, depending on its material properties (mainly if its categorizable as a metallic, ceramic, or a polymer). If the sphere is of huge mass, it could have the inward force to resist deforming just due to gravity. It just comes down to the balance of forces until we start imagining high enough speeds where no inward force is enough, and then how the sphere breaks down is based on the forces dictating how its material behaves when a force is applied. It may also be worth mentioning that some rotational velocities are simply too fast for any material to withstand solely by its own material strength. At those speeds and higher, the only thing that could hold your sphere together is the super high gravity of a black hole. So now your sphere is the (possibly) infinitely dense core of a black hole, but let's keep speeding it up. As we do, the black hole creates greater frameshifting and light is able to orbit nearer and nearer the black hole, shrinking its event horizon. It's is a law predicted by general relativity that a singularity can never be exposed to the universe (hard to explain, maybe good to look up "naked singularities"), so with an increased spin shrinking the event horizon, there must be a cap on how fast the black hole is physically capable of spinning due to a higher speed shrinking the event horizon to the point of singularity exposure. This puts a cap on the spin to be some fraction of the speed of light. If we increase the mass of the black hole enough, we can then get your sphere "stably" (although violently) spinning at close to the speed of light (some black holes spins have been measured at over 95% the speed of light). At least to my knowledge, the story ends there.

[@feynstein1004]

+pendalink Thank you for the informative reply. That was my guess too. And as you probably guessed, I was thinking of a black hole. I think that because of the conservation of angular momentum, the black hole must eventually be spinning so fast that in spite of the enormous gravity, it can't shrink any further and reaches a kind of equilibrium, if you will. I just don't like the idea of a zero-sized, infinitely dense singularity.

One thing I'm trying to wrap my head around: When the switch is closed, will any current flow at all through the diode? Or will all the current be contained in the Inductor's Magnetic Field? (For the Boost Converter)

During that time voltage across diode is -(load voltage) , reverse biased Hence zero current flows through diode ideally

[@EugeneKhutoryansky]

[@robertocardenosa493]

Why does the diode block the current when the switch of the transistor is on? I mean the current is represented as going on the "allowed" direction so why is it being blocked?

[@EugeneKhutoryansky]

When the transistor is on, the capacitor creates a reverse voltage across the diode, causing current to try to flow through it backwards, which the diode blocks.

[@arimirsky2769]

At 8:20 why would that be problematic? Wouldn't there be temporary resistance across the capacitor, making the circuit stable?

[@jimstanley_49]

No. The main thing to consider is the voltage across the "switch." A transistor can only hold back so much voltage before it lets the magic smoke out. Once it reaches its limit, even the small amount of current the capacitor lets through will fry it.

You need a driver circuit for the switch, which is a comparator where as inputs you have a repetitive signal ( sawtooth wave) and another costant signal that you can control, so you get duty cycle that you want.

Long question, please answer if possible. Inquiry on the principle of voltage and current in the power conversion system To supply 1.500 KW, a transformer will be installed in the substation. Is the voltage and current of the first input part converted based on 1000V and 50A? 2. If number 1 is correct, the AC-DC converter uses 1000V 50A as it is, not for conversion, but for smoother 1000V DC? or If it is not number 1, is it parallel connection of 380V, 1250A inputs -> 10 units of 1000V, 50A each? 3. AC-DC converters use a transformer to convert current and voltage. → The primary and secondary power must be the same, so when the voltage on the secondary side goes down, the current goes up. Buck DC-DC converter adjusts the voltage through LC circuit + switching ON and OFF. Duty ratio 1 (if ON 100%) → 1st voltage = 2nd voltage Duty ratio is stepped down to secondary voltage, but as the ON time becomes longer, Voltage rises further within the stepped-down voltage range What is the current principle? It is said that the output current does not decrease even if the switch is turned ON and OFF. The reason for the decrease is the ratio between the output current and the input current. According to Kirchhoff's current law, it can be understood as incoming current = outgoing current. From the point of view of input power V1*I1 = V2*I2, the current is the same, but V1>V2 becomes V1>V2. do. (I'm not sure what part I'm not understanding. But in a Buck DC-DC converter, the principle is that input power = output power just like a transformer. I'm not sure what part I'm not understanding.

But would it be the opposite polarization? I want to know what actually happens without thinking according to the conventional current.

Galaxy- BH Dissipate BIG amout of particles, they slide to Edges of galaxy and form hydrogen there.(they move faster then light, so we can not see them. hydrogen formation start after they lose energy\speed). then formation of first starts and slow muving to central BH. this how galaxy sustane existance.(not all but most part) and dark matter is a gravitatinal after image of particles that move faster then light.(most likely) 3. Can mass\energy of particle be prolonged in space, be in more then one place at time? (yes if it move faster then light) 4.Gravity- is energy exchange aftermatch. (it is like Electromagnetism, but with very high speed of polarity change)(so it worck in bouth direction in same time to compare to us) (like cinematic effect for video) i know it sound like Unbelievable but how to check? what do you think about it all? best regards Dynin.A.I.

I can be wrong but this what I believe. (Sorry if my English not so good) 1) Motion cannot exceed light speed since is made of forces that only move light speed. That why things slow down("time") if you move them, otherwise the parts would be faster than light but they cannot do. If motion increase more than light then the inward force that create regular matter lose its properties and matter cannot exist. 2) Only smallest hypothetical exotic elements which compose to matter we know could move so fast. Galaxy is pushed together by reduced opposition forces in center. Since the stars are distant it is not the same as single star. The opposition come from forces from everywhere in universe which emit and have irregular interaction for matter so we do not detect. I believe dark matter can be explain from this instead but this other idea is interesting too. Maybe many reasons for things we do not find. 3) Maybe. It all manifest from properties and respond to surrounding forces. So it would be affecting 2 places at same time if possible. We think something exist somewhere when we can detect how it interact with equipment. Maybe if property to escape balance of surrounding forces it can happen. 4) Yes. I think you have something. I believe forces from entire universe are balanced and constant speed create like direction rate pressure but not like particle pressure. Polarity change big part of that. I think something like you say. Maybe it possible change a balance of surrounding force (momentum) by reflecting some polarity and passing other polarity in some directions? I do not yet think how to test these idea. Are you thinking to make way for interstellar travels? :)

The clearest way of looking at the inductor's operation is that when the battery is charging the inductor, the inductor is behaving like a resistor to the battery's DC current being pushed through it. This resistance is being caused by the back EMF being generated in the inductor while the current through the inductor and magnetic field around the inductor is increasing. When the switch is opened, the inductor then behaves as a battery due to the forward EMF being generated by the inductor's collapsing field. The back EMF and the forward EMF will always be of the same polarity.

I explain inductors in detail in my video at kzbin.info/www/bejne/q5yld4Oojc5-jaM

Hello I am a high school student living in South Korea. The reason I am commenting is to write a physics school record for college. I learned the electromagnetic induction phenomenon during the physics class and I am going to make a railgun and write a school record So I saw a video of 'physics videos by eugene khutoryansky' while researching the data and I want to ask for advice. 1.Does 'charging' in the video mean capacitors? 2.If you mean a capacitor, will the voltage be higher if you use a good capacitor? Answers I'll wait

I am not sure I understand your question, but I have a detailed video on capacitors at the following link. kzbin.info/www/bejne/nJCwi4Gpetash9k
