I understand this. My question is: Why does the circuit loop have to be completed back to the -ve terminal for it to work? If the +ve end of the battery has a deficiency of electrons, why would the electrons NOT flow from Earth ground to the +ve terminal when connected? I mean I understand how...

lets say I dig a deeeeep hole and put in a conductive metal rod. This will provide my Earth Ground. Now if I connect my +ve battery terminal to this wonderful metallic connection (while leaving the -ve terminal floating) ... will I have charge transfer? Our home power outlets ... their...

Hi all, If I take a battery (lets assume a car battery) and connect the +ve end to Earth Ground and leave the -ve end floating. Why is there no charge transfer from the battery to ground? I've read up on a variety of threads regarding this question on this forum. Haven't quite found my...

Jeff Reid, Great links! Really helps to show what Borek and the others have been trying to explain since the beginning.

I understand what you are trying to say. Thanks for you earlier post. It helped me look at the phenomenon in a different perspective.

If your box has negligible mass, then the entire box would also go up as the air comes out from the bottom hole. Which means your hot air is going up AND down =) I don't know if you can use this thought experiment.

actually my previous comment sounds a bit silly. let me explain myself. what I meant is maybe he's looking for an explanation of buoyancy itself using a kinetic model...

maybe the question can be rephrased to "what causes buoyancy at a molecular level"?

Hi all! This may have been previously posted before but check it out! Just discovered this today. It's really cool. Great for getting an intuitive feel for what is happening in circuits. Try hovering over the components to get simulation info of each component...

Thanks guys! It makes more sense when thinking of the power. I think the thinking that was confusing me was that I was thinking the NUMBER of electrons going into the transformer has to be the same as the number coming out. But I can't think of it like that since the two ends of the transformer...

Hi All, I'm familiar with this analogy: "The voltage is equivalent to the water pressure, the current is equivalent to the flow rate, and the resistance is like the pipe size." -HowStuffWorks.com Power comes to our house on high-voltage, low current lines. Through a transformer, it gets...

f(x) = (2x^3 + 4x^2 - x + 1) / (-x^2 - x + 2) The limit of this function as x approaches infinity is the oblique asymptote f(x) = -2x - 2 This can be verified by performing long division with the two polynomials to get: f(x) = -2x -2 + (x +5)/(-x^2 - x + 2) as x -> infinity, the term (x...

yeah I don't know much about black holes to be of help much either but.. at what point do stars implode under their own weight to become black holes? maybe if you knew the answer to that it might help...
