Place to learn circuits 2? ac circuits class

AI Thread Summary
The discussion focuses on finding resources for learning about AC circuit theory, specifically regarding lead and lag calculations, and Norton and Thevenin equivalents. A user is seeking free educational materials due to budget constraints for textbooks. AllAboutCircuits.com is recommended as a valuable resource, although it follows the electron direction convention for current flow. The importance of understanding electron flow in circuit analysis is also highlighted. Overall, the thread emphasizes the need for accessible learning tools in electrical engineering.

im taking circuit theory 2, which is all about ac circuits, but don't have enough money for a book
need a place to learn about how to calculate lead and lag based on the inductance and capacitance, nortons and thevinans and all that stuff but in the context of sinusoidal currents and voltages
 
Engineering news on Phys.org
tyvm! don't know why that didnt show up on google
 
Take note that AllAboutCircuits uses the electron direction convention for current flow.
 
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...
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...
