Voltage waveform analysis

    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
