Complex S = V x I*.
V = A sin( Wt + beta) ; I = B sin(Wt + phi) ; Theta = (Beta - Phi)
S = (A angle_beta) x (B angle_phi*)
Beta > Phi = we will get an positive reactance of j (positive Theta)
Phi > Beta = we will get an negative reactance of j. (negative (Theta)
Looking at the power...
Hi, I don't mean to jack the thread but I'm also EE and im preparing for the FE as well. Do you mind sharing the information that you have with me as well?
thanks
