SUMMARY
The discussion clarifies the difference between Vrms (Root Mean Square voltage) and AC voltage values. Vrms is a measurement that reflects the effective voltage of an AC signal, particularly for sinusoidal waves, and is typically measured using a multimeter or oscilloscope. The RMS value is directly related to the heating effect of the signal, as it represents the equivalent DC voltage that would produce the same heating in a resistive load. For sinusoidal signals, the RMS value can be calculated by multiplying the peak voltage by 0.707 (or \sqrt{2}/2).
