The last animation is what I needed for so long. In earlier stages, it wasn't clear where the energy goes, but in the last one, you clearly stated that the energy that is carried out by atoms is lost because of the heating in the wire and the light that is emitting from the lightbulb. Thank you so much.

Your comment took me back to when I started studying electrical engineering 😃. I had the same question that you commented. But if you do the maths it becomes obvious. The current through a capacitor is I(t) = C dV(t)/dt where C is the capacitance of the capacitor and V is the voltage applied across it in time t. If V(t) is a sine function (i.e., AC voltage), I(t) will be cosine. Thus we get 90° phase difference. Similar relationship also exists for an inductor. If you are curious to know more, you can read Wikipedia's capacitor page under "theory of operation".

@@kirkhamandy I love your comment. Adding to that, if you want to go Even Further then you should recall that Maxwell equations were the collection and complete understanding / unification of prior scientists equations like Faradays equation , or even Biot Sevart's law. Or even Amperes Law! All within maxwells equations. Though maxwells change from integral form to differential form was very a very profound change at the time since it was such a different way to view E&M at the time. Instead of being the sum of parts it is viewed as the differentials of hidden Fields as they change. Quite a mathematical way to change how Physics was being done in that time period.

Nice video! Though I still can't visualize in the end on what happens if the voltage and current is 90 degrees out of phase. Will the energy just move back and forth without transferring to the light bulb? And given that the energy has to be lost by the resistor, how will the energy source compensate with that? Thank you for your response!
@EugeneKhutoryansky
@EugeneKhutoryansky 3 жыл бұрын
The voltage and current can be 90 degrees out of phase only if the load has no resistance, as in the case of an ideal capacitor or an ideal inductor. Therefore, if the load is a light bulb, the voltage and current can't be 90 degrees out of phase, because the light bulb has at least some resistance to it, and it is this resistance which dissipates power. For an ideal capacitor or an ideal inductor, they can't dissipate power, they can only absorb energy and then release it back again. And yes, the energy source will keep adding energy to the system to compensate for the energy lost in the resistance of the wires.

Being completely in phase is not desirable in power circuits. It's true that the reactive power represents an opportunity for loss of energy due to resistance for less power transmission. However this reactive energy also provide stability to the voltage and current of the power circuit. One example is the with solar power in a local grid. Solar provides almost no reactive power and therefore turbines or other sources of reactive power must carry a larger percent of reactive power, reducing their efficiency, increasing their costs and often CO2 emmision. Other than that the video was excellent.

If anyone like me had a hard time seeing why in-phase had net flow of energy vs out-of-phase not having it: Blocks are being carried away from us down the circuit, and they’re *not* being brought back towards us when it’s in phase. If you could follow one specific block you’d see it working its way down the line. (At first I thought they meant net flow of blocks from the left “lane” of the circuit to the right lane…silly me.)

Nice video! Although defining Real and Reactive power by the phase difference between current and voltage is only valid in the case sinusoidal signals. A more general way to define real power and apparent power is: Real = avg(current(t) * voltage(t)), Apparent = rms(current(t)) * rms(voltage(t)).

One question: So the "E" blocks are supposed to represent the energy stored in the system? If so, the energy is stored in the magnetic and electric fields around the wires. The loop formed by the two conductors has a magnetic field inside it, and the energy in this field increases and decreases twice per cycle, once for each time the electric current reverses. Likewise, the electric field in the gap between the wires stores energy and increases and decreases twice per cycle, once for each time the voltage reverses. The net power delivered in either case is no power, but an electric current is present in the wire which does dissipate resistive power, as a wire allows a current to flow ideally instantaneously whenever a voltage is applied across it (and not with a lead or a lag).

0:41 The phrase "voltage difference" is redundant here. Voltage is already a difference (of potentials).

Question. How do you justify that higher voltage particles carry higher energy, give that it was an arbitrary designation that electrons have negative charge? Say if in an alternative timeline the electron was designated to have positive charge, then then energy flows backwards by the logic in this video, but it shouldn’t matter in reality?

Power=Voltage*Current Current=Voltage/Resistance If the direction of the voltage changed, the direction of the current would also have to change, and negative * negative = positive

7:45 Why only on the magnitude of current? Isn't P = V.I = I^2.R = V^2/R ?
@EugeneKhutoryansky
@EugeneKhutoryansky Жыл бұрын
In these equations, when applied to the power lost in a section of wire, V refers to the voltage drop across the wire, not the voltage of the voltage source. The voltage drop across the wire can be derived from the current and the resistance of the wire.

Thanks. 1:15 I still have a hard time realizing whether the net flow of energy boxes goes from left to right. Doesn't it go from right to left ? And I guess they get consumed in the load. Was this shown in the simulation?

Hi thanks for the video. I understand the concept of energy boxes of charges and why they increase or decrease depending on their "height", but why and how are they transfered from the "higher" charges to the "lower" charges ? Also I don't really understand what can make the current and voltage more or less in-phase.
@EugeneKhutoryansky
@EugeneKhutoryansky Жыл бұрын
They are transferred through the energy stored in the electromagnetic fields between the wires. The extent to which the voltage and current are out of phase is determined by the amount of inductance and capacitance in the circuit, as described in my video at kzbin.info/www/bejne/sICag42QjJWqibM

🌹🌹🌹🌼🌼 My mentor is back with another outstanding video, 😍😍🙆🙆💖💖💚💚. My mentor , what happens at atomic scale inside a wire by which we can say that the power Lost is equal to (current × resistance) regardless of the voltage? Will you please make a video on this topic. This topic is really confusing. This concept is of same confusion as that of Bernoulli's principle . 🤠🤠🤠 But we all are sure that you will one-day clear this misconception in the same way in which you brilliantly cleared the misconception of Bernoulli's principle. 😘😘

I am glad you liked my video. Keep in mind, when I referred to the voltage, I was referring to the voltage difference between the two wires. This is not the same thing as the voltage drop across the resistance of the wire, which is proportional to the current. Thanks.

7:24 - Some of the energy is lost in the resistance of the wires. - the way I see it, the energy is not 'lost' - it is just dissipated as thermal (non-visible) heat, just like the bulb dissipates thermal and visible energy. Dropping the 'E' boxes from the wire resistance then isn't technically correct (could be interpreted as gravity absorbs it?) when the light bulb gets a yellow sphere/photon attached to it. The 'E' boxes dropped from the resistance should imho have a brown/lower-temp sphere/photon - and radiated out from the resistor - just like a real world resistor gets warm when it dissipates energy. Great video though, hope you don't take my view as negative - it is in fact the opposite..

@@lmmao406 Conservation of energy says no energy is lost, it is transformed - into heat in this case, which is also non-visible light (It can be seen using a FLIR camera) Reactive power can melt wires, if the power dissipated is high enough - and that energy isn't lost, it is a hazard ;ø)

Why don’t the sine waves appear to be out of phase by 90 degrees at 3:50? Looks more like 45 degrees.
@EugeneKhutoryansky
@EugeneKhutoryansky 3 жыл бұрын
That is what 90 degrees phase difference looks like. Keep in mind, if it was 180 degrees, the two waveforms would be the opposite of each other (multiplied by negative one). Therefore 90 degrees is halfway to this point.
