SUMMARY
The discussion centers on the misunderstanding of how an AC voltmeter measures a DC signal. The voltmeter, when connected to a 24V DC supply, reports an average voltage of 24V. However, since it is designed for AC measurements, it incorrectly applies a multiplication factor of 1.11, which is used for sine waves, leading to confusion about the RMS value. The key takeaway is that the AC voltmeter misinterprets the DC signal, resulting in an inaccurate representation of the voltage.
