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 'What happens if shielded cable has a short to the shield?'

While I was rolling out a shielded cable, a though came to my mind - what happens to the current flow in the cable if there came a short between the wire and the shield in both ends of the cable? For simplicity, lets assume a 1-wire copper wire wrapped in an aluminum shield. The wire and the shield has the same cross section area. There are insulating material between them, and in both ends there is a short between them. My first thought, the total resistance of the cable would be reduced...

Thread 'Underwater piezoelectric sensor array receive sensitivity'

Hi all I have some confusion about piezoelectrical sensors combination. If i have three acoustic piezoelectrical sensors (with same receive sensitivity in dB ref V/1uPa) placed at specific distance, these sensors receive acoustic signal from a sound source placed at far field distance (Plane Wave) and from broadside. I receive output of these sensors through individual preamplifiers, add them through hardware like summer circuit adder or in software after digitization and in this way got an...

Thread 'Question about bonding ground and neutral'

I am not an electrical engineering student, but a lowly apprentice electrician. I learn both on the job and also take classes for my apprenticeship. I recently wired my first transformer and I understand that the neutral and ground are bonded together in the transformer or in the service. What I don't understand is, if the neutral is a current carrying conductor, which is then bonded to the ground conductor, why does current only flow back to its source and not on the ground path...
