What is the peak value of a sine wave with RMS 50 V?

Explanation:
A sine wave’s peak value is larger than its RMS value by a factor of √2. For a sine wave, Vrms = Vpeak / √2, so Vpeak = Vrms × √2. With Vrms = 50 V, Vpeak = 50 × √2 ≈ 70.71 V. That’s why the peak value is about 70.71 V. The other numbers come from mixing up RMS and peak or applying the wrong factor.
