Homework Statement Is NBr3 a polar or nonpolar molecule, please draw a lewis structure and a perspective drawing. Homework EquationsThe Attempt at a Solution it is polar because of dipoles?

This is the capacitor i am basically making but eith my dimensions. I am going to riund the edges of the protruding aluminum but i think i should be fine. So with that equation do i only need aluminum 12 x 12 them dielectric then another piece of aluminum 12x12?

I legit just figured this out and then looked in my email and found this. Lol yes that sounds right thank you!

its going to be very hard to sand down aluminum foil lol. its a piece of polyester with aluminum foil on top, and maybe several layers. all i want to know is why i calculated such a low area, please help me.

yes, my dielectric is able to withstand 15kv

M is meters, my science teacher said it had to be in meters, it is normally 0.005" thick.

Ok, so I am am trying to make a homemade capacitor that is 4700pf and 15kv. polyester at 125 micrometers thick can withstand 15kv so were good. here is the equation i used C=ε0 K A / D Where C = capacitance, ε0 is epsilons constant, K = dielectric constant, A = area of aluminum foil, and D is...

Now from reading wiki i understand there are Pin-bar and non pin-bar, non pin-bar is what people have moved to today with the spark gap. but i read that "These first 'Pin-Bar' TEA lasers, operating at around one pulse per second, were easy and cheap to construct. By operating at atmospheric...

Heres te thing though and i know this sounds dumb. I always like to create new things, finding better ways for things to work. Everything can be make better, cheaper. Yes i am a kid but I believe if put enough research in i can find a better way. Call me dumb but look at how many thing thought...

if i have a lower nm wavelength like UV and a little bit of a lower W per pulse, since there are more electron volts per photon will i have a better chance at ionizing?

You have to read the description cause the video is just the ionization

In the video of the guy that achieved air breakdown he used 2 lasers focus to one beam, would tgat help my case

please read the first few lines in the introduction here https://arxiv.org/ftp/arxiv/papers/1407/1407.0464.pdf it looks like few ev so higher nm, and microsecond pulses should work

The output is 250000W not 250mW sorry about that

So i have been looking at a 1microsecond pulsed 250milliwatt 980nm laser. I watched a video where a guy outputed 50millijoules at 5 nanoseconds and achieved air breakdown. I am wondering since maybe mine is higher energy it will do the same or i need faster pulses?
