First of all, by voltage, it wasn't clear whether ledjr was referring to instantaneous or RMS? I'm guessing RMS. Secondly, was he asking about ANY periodic AC voltage in general or the common sinusoidal one? I'm guessing sinusoidal only.Originally posted by ellea@Nov 25 2004, 09:12 PM
Hi ledjr,
Now here is the formula for v (notice lower case which means time varying)
v=Vp Sin (2*pi*f*t)
Now as you can see the bigger the f the smaller the (sin (2*pi*f*t))
And you also know that that value does not exceed one so the smaller it is the smaller your v
so if you want your v big a high frequence your better off starting off with a high V peak
I hope that answers your question.
As for the ratio. Man that's a long euation to solve :unsure: :unsure:
Now if you got time start with v/Vp= Sin (2 pi f t) and derive the f
Good luck
