Unknown Voltage Source and Current

AI Thread Summary
The discussion centers on determining the voltage across a 9.1-ohm resistor in an unknown voltage source circuit. One participant suggests reviewing a previous thread where a similar problem was solved step-by-step. They recommend using nodal equations or loop equations to analyze the circuit effectively. The emphasis is on revisiting the original solution for clarity. Understanding these methods is crucial for solving the current problem accurately.

clue: what's the voltage on the 9.1 ohm resistor? then just keep going.
 
Pantera, if you look closer https://www.physicsforums.com/showthread.php?t=159391" You might notice that I already solved a similar problem for you. I even did it in a step by step ;) So, I guess that you've to go back to the original thread and read it one more time, because the solution is there, you just can't see it. So take a better look ;)

You can either solve it by applying nodal equations as I did for you in another thread, or you can write two loop equations the describes the circuit.

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...
