Question

If A standard electrical outlet provides a 120-V,60Hz sinewave. Would the average voltage be 108.08616?if the peak to peak voltage is 339.36

Answer 1

if the peak to peak voltage is 339.36

Answer 2

Do you mean: a standard outlet provides 120V AC with 60Hz ?

Answer 3

yeah i forget that

Answer 4

The average voltage does not depend on the frequency!

http://www.electronics-tutorials.ws/blog/average-voltage.html
\(\dfrac{1}{2}V_\text{pk-pk}=V_\text{pk}\)
So we can use the equation at that link to find that
\(V_\text {ave}=\dfrac{2}{\pi}V_\text{pk}=\dfrac{1}{\pi}V_\text{pk-pk}\)
