Q: A certain sin wave has a positive going zero crossing at 0° and an rms value of 20V. Calculate its instantaneous value at each of the following angles: (a)15° (b)33° (c)325°
So my Vp=28.28
But since my starting point is at 0° would that mean each of those angles are lagging and i would have to use the formula: y=Vp sin(θ-Φ)?
Or would i just use y=Vpsinθ
Thank you.
