Ohhhhhhhh I hadn't thought of that work being done... makes sense! Can that lead to the voltage being HIGHER than the initial source? Or does it cap off at the voltage of the battery/van de GraAff? Thanks again, blown away by that response time by the way!

Question: If you charge a capacitor circuit and then separate the capacitor, does voltage increase beyond the initial source? It seams counter intuitive that if you plug a 9 Volt battery into two metal plates and pull the plates apart that you'll get massive voltage spikes, but that's what the...

Question: Is there a way to calculate the radius of an electric field? By that I mean, say we have a cathode on one side, how far away can the anode be? Is there a way to calculate this? I'd imagine it would need to be experimentally derived due to the number of variables (shape of object...

You guys are too good! EDIT: Quick questions, first, for future search ability, what is this formula called? secondly, what does "e" represent? Is that e as in 2.7...? Thaaaaaaank you everyone

That was an easier answer than I could dream for! Thanks again mfb!

Good afternoon, I hope this is in the right place... Anyway, diving right in- Say I have a classic CRT- How do I calculate the energy, in eV, that the electrons have upon reaching the anode? Also, is there a way to derive the speed of the electrons as well? See the attached image to...

Beautiful- Thank you again for your time!

Ohhhh that makes sense- I am ashamed to say how long I spent with the right hand rule trying to get them to add up! Anyway, just to make sure I'm on the same page, Is it just a series of increasingly powerful/ timed anodes to pull the beam forward? I would figure as much... See the attached...

Ohhhh I've worked with Lorentz prior, I totally forgot that they have a vector form... Anyway, so secondary question: How do magnets speed up electrons, like we see in CRT's and medical equipment? Wouldn't any magnet automatically slam an electron beam into the wall in order to be perpendicular...

Good afternoon, Question: Say I have an electromagnet at a 45 degree incline from an electron beam. This electromagnet is exerting 0.75 Tesla on the beam. How can I calculate the vector that the electromagnet will exert on a particle? Note, this is for my own curiosity, not for any homework...

Problem- 0/0 = ? This has kept me up pacing the Floors many nights now, but what is 0/0? It's either, 0/0 = 1, because anything over itself is 1 0/0 = no solution because you cannot divide by zero Or, 0/0 = infinate, because say you have an empty jar of m&m's, how many other jars could you...

Who knows? EVENTUALLY we may hit an end... But at 5 trillion digits I wouldn't hold your breath... Regardless of its precise location on a number line, it's irrational, but real

You're never going to be perfect, but with 5 trillion digits, I think you are going to be fine in a practical sense- at that point you start to run out of molecules in the paper to be so precise!

I should clarify, Put it on a number line- *beautiful demonstration* |------------------|------------------| -5 0 5 .i, or sqrRt(-1) *note, i is on its own, because i is an introvert- no really though I just doesn't follow logic...

Pi is real, just irrational as well- because you can graph it, it's real- like try graphing i (or the square root of -1), that's when numbers get imaginary- Oh imaginary numbers... Gotta love math sometimes :D
