What Does a Shifted Voltage Waveform Indicate About Load Characteristics?

Click For Summary
SUMMARY

The discussion centers on analyzing a shifted voltage waveform across a 15W resistor load with an applied voltage of 230V AC at 50Hz. The waveform indicates characteristics of the connected load, particularly its impedance and phase relationship to the voltage. The Analog to Digital conversion occurs at approximately 1690 samples per second, which is relevant for capturing the waveform accurately. Participants express confusion regarding the specifics of the waveform and the meaning of the 15W specification, questioning whether it refers to resistance or power.

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
