Question #87594

Calculate the voltage value of a sine wave at 135° whose VRMS= 1000 VAC. Show all work.

Expert's answer

Usually a common sine wave is written as

where "\\omega=2\\pi f" - angular frequency,

"V_{RMS}\\sqrt{2}=V_{amp}" - amplitude (pike or maximum) value of the voltage,

"\\phi" - phase angle.

So in our problem the maximum amplitude voltage value is "1000\\sqrt{2}=1414.2\\text{ V}".
