What Does a Shifted Voltage Waveform Indicate About Load Characteristics?

AI Thread Summary
The discussion centers on analyzing a voltage waveform across a 15W resistor load with an applied 230V AC at 50Hz. Participants express confusion regarding the waveform's characteristics and the meaning of the 15W specification, questioning whether it refers to power or resistance. There are requests for clearer information, such as a schematic to understand the waveform's origin better. The reliability of the image links is also a concern, as some users report issues accessing the waveform image. Overall, the conversation highlights the need for more context to accurately interpret the load characteristics indicated by the shifted voltage waveform.

This the voltage waveform across a resistor load (15W). The applied voltage is 230V AC at 50Hz. What can be inferred from this? [ the Analog to Digital conversion of Voltage happens at around 1690 Samples per second]. What can we infer about the connected load from this waveform?

Thanks for pointing out. I don't know why its not working. Included an alternative link anyways.
 
Not enough information. The question doesn't really make sense to me. Can you draw a schematic and show where this waveform was taken?

230V 50Hz is going through something that provides this waveform across a resistor? Are the numbers the actual voltage across the resistor? What is the 15W about? Did you mean 15 ohms?
 
I abhor those spammy image sites

here's the image for the benefit of all

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...
