    12:46 There’s a small mistake said. KCL is not always true. It’s true there is a capacitance between the wire and Earth. It’s also true the current I_1 is not the same as I_2. However, it’s false “current *must be* leaking into the ground” as ElectroBOOM said at 12:54. No, not necessarily there is a leak of current. That is *one* possible reason, but not the *only* reason. Another reason could be that charge is simply accumulating somewhere in the wire, or in other words the charge density is not constant. I mean, suppose we have an insulated cable. Then of course no charge inside the copper wire is leaking into ground, because the insulation prohibits that. So the reason current in is not the same as current out is because the charge density at each point in the wire is not the same. To further proof my point, you can read about the law of conservation of charge, which in differential form states in words that “the partial derivative of the charge density with respect to time is equal to the negative of the divergence of the current density”. KCL is derived from this law assuming the charge density is constant, meaning its time derivative is zero.

    Please make a similar video showing the current flow in a battery-fueled circuit.. i've read a many forums and people simply can't get to agree of how does the current flow in that circuit and how does the electrons flow inside a battery (well i personally think that there is no flow of current inside a battery because there is no closed loop in it but i think that the negative therminal pushes the electrons to the positive terminal so they come out from the positive therminal to the loop/circuit when discharging and coming back to the negative am i right?? But that leads us to the next question, how can electron go through a negative and inside to the battery? That is impossible, leads me to think that there must be a positive and negative side of that negative therminal so the electrons go inside battery through the positive side of the negative therminal, right?) And the charging worx exactly the opposite way? I would like to make it clear..

    Alright so I'm back again, and I've just realised an issue with lumped models. If in a lumped model nothing radiates and messes with other stuff, does that mean that, given our lumped setup, radio transmission is impossible? Now there's a thought to keep you up all night >.

    So no free energy. Your debate with lewin makes me want to know about this 'radiant energy' of master ivo. What is the longitudinal magneto dielectric wave? If such a longitudinal EM wave is to exist what are it's implications theoretically? Somehow we must be assuming that the interpretation of maxwell's results have yet have this result shown or derived form it: that is longitudinal em wave exist as some mode of energy transfer that becomes significant under certain conditions. Ivo uses these bifilar inductive coils (tesla?). Can you replicate these results? Is there some measurement I'm missing that shows this energy?

    Ok so, if anyone is good at electrics or anything that would be great, I went to heat up my tea in the microwave earlier, so I stuck it in, shut the door and everything was ok until I went to turn on the microwave at the plug (I'm in the UK), my right hand was on the microwave not sure if it was the metal side panel or the buttons, and I turned on the plug with my left, and I got a pretty bitching shock on both my fingers, anyone have any idea what the hell just happened? The microwave was ok to use after that, and heated my tea up alright with a couple plastic gloves, but still kinda worried about using it from now on. It was pretty shocking I guess you could say

    I disagree with the random association of polarities. Wouldn't the battery always have to have polarity in reverse to the components for the sum to equal zero. For example If you have a single loop with a battery and resistor, if you label the battery in the same manner as the resistor you will end up with +V +V=0 But from my understanding the sum of the voltages around the battery and resistor, if you take both of them as positive, could not be zero, Either the battery or resistor/component has to be negative. Can someone please explain.

    This video is so helpful with high school physics. Really helps understanding everything. In Finnish high school books those are called the first and the second law. I just now looked it up and realized that we also use current and voltage in the names, but the books just don't tell it to us.

    This is not for beginners. It's probably TAFE cert 3 electrical. It fits uneasily in the cert 2 syllabus end but is presumed to be easily understood for Elecronic Engineering, week 1. You will need to do a lot of work to understand it, and Jim Pytel and Ben Eater are good exponents.
