    Diodes Parallel
AI Thread Summary
Adding voltages in parallel using diodes is not feasible, as one diode will become reverse biased, preventing current flow. The discussion highlights that using superposition theorem is not applicable in this scenario. The consensus is that the output voltage will be limited to the forward-biased diode's voltage. Overall, the concept of combining voltages in parallel with diodes is clarified as incorrect. Understanding diode behavior is crucial for accurate circuit design.

I'm sure you can't but I don't really see why not. Its been ages since I've done anything like this and I just wondered, I can't think of a way to varify it like I don't think you can use superposition theorm.

My question is shown in tha attatched picture.

Thanks very much.

you will get 6V because the top diode will be reversed biased.
 
Ofcourse! Simple and beautiful explination.

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...
