Does anyone know where i can score a site with lots of problems pertaining to electronics equipment. Trying to understand the basics (resistors now) and when i google it i just get tons of crap but no problems to solve. anyone? Thx :)

I think you should get a book instead. Amazon sell used textbook really cheap.

The homework section of this site?
 
Hey perpc...

I attached a short 4 page summary of electric basics. I wrote it a couple months ago and I feel it is written so anyone can understand it. It leaves out all the nonsense and just points out what you need at first. Work your problems and look at the basics I layed out. You'll be pretty good in no time...have fun.

Thread 'Weird near-field phenomenon I get in my EM simulation'

Thread 'Weird near-field phenomenon I get in my EM simulation'

I recently made a basic simulation of wire antennas and I am not sure if the near field in my simulation is modeled correctly. One of the things that worry me is the fact that sometimes I see in my simulation "movements" in the near field that seems to be faster than the speed of wave propagation I defined (the speed of light in the simulation). Specifically I see "nodes" of low amplitude in the E field that are quickly "emitted" from the antenna and then slow down as they approach the far...

Thread 'EMF (Electromagnetic Field) & EHS (Electromagnetic Hyper Sensitivity)'

Hello dear reader, a brief introduction: Some 4 years ago someone started developing health related issues, apparently due to exposure to RF & ELF related frequencies and/or fields (Magnetic). This is currently becoming known as EHS. (Electromagnetic hypersensitivity is a claimed sensitivity to electromagnetic fields, to which adverse symptoms are attributed.) She experiences a deep burning sensation throughout her entire body, leaving her in pain and exhausted after a pulse has occurred...
