I've been checking my mailbox with so much anticipation for the last couple of days. I really hope it's today. I was so confident I passed when I first took it, and now I can't even remember any of the questions. I just need it to be over.
Here is sort of how I thought it through.
kvar = 3*Vp*Ip*sin(cos-1(pf)) = 3*(Vp)2/Z*sin(cos-1(pf))
In the case of the capacitor it tells us what the kvar is for the rated voltage then it asks us for the kvar at a lower voltage. The only variable that changes is the voltage so you can then set...
