    Currents Loops
AI Thread Summary
The discussion focuses on a user's difficulty with loop currents while revising for an exam. They encountered issues with sign errors in equations for shared resistors in a specific example. After receiving encouragement to share their work, the user realized they were mistakenly not adding currents that flowed in the same direction. This clarification helped them resolve their confusion, leading to a better understanding of the topic. Overall, the exchange highlights the importance of correctly applying current direction in loop current analysis.

Help - Loops Currents. :(

hey there I'm revising for an exam and i can't really do loop currents
i was trying to do this sum http://mathonweb.com/help/backgd4.htm (example2) but kept getting the rong sign for equations (for shared resistors):( could someone please explain to me!
thanx in advance.:cry:
 
Engineering news on Phys.org
Can you show what you've done? Maybe we can help then.

Regards

P.S. Welcome to PF.
 
alright thanx..i'm sorted now..i was making a silly mistake.. of not adding the current since they were in teh same directions! we've done example of the opposite so that's why i subtracting :) thanks for the reply.
 
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...
