SUMMARY
The discussion centers on calculating the root-mean-square (RMS) voltage across a 1500W device with a peak current of 5.4A. The user correctly applies the formula for peak current, deriving an RMS current of 3.82A. Subsequently, they use the relationship between power, RMS current, and RMS voltage to find the RMS voltage, concluding it to be 392.84V. The method employed is confirmed as accurate, despite the user's initial uncertainty regarding its simplicity.
