How do we know when to use either of those equations? For example, one problem below uses V^2/R in it's solution while the next problem uses I^2 x R.

On a question like this, how would one know to use single phase vs three phase values? The solution converts KVAR to single phase. I'm assuming its because each 100 KVAR capacitor in the wye arrangement is assumed to be reactive power per phase and not the total reactive power?

Thanks for making this make more sense.

Can someone please explain to me where the pu unit impedances come from in the below problem? This is from the ENG Pro Guides Final Exam.
