The peak-to-peak value of an AC voltage whose RMS value is 190 V?

Explanation:
For a sinusoidal AC voltage, the peak-to-peak value is twice the peak amplitude, and the RMS value relates to the peak by Vrms = Vpeak / sqrt(2). With Vrms = 190 V, the peak is Vpeak = 190 × sqrt(2) ≈ 268.74 V. The peak-to-peak value is 2 × Vpeak ≈ 537.48 V. So the peak-to-peak value is 537.48 V. The other numbers correspond to the RMS value or the peak value, not the peak-to-peak.
