I’ve run across a couple of problems for which I feel that I am missing a mathematical foundation. For example #131: A 3 phase capacitor rated at 240 V and 110 kVAr has been proposed for correcting the power factor of a 3 phase induction motor operating at 208 V. What will be the reactive...

I thought that I had a pretty good understanding of when to use sqrt 3 and when to not use it. However, I was working problem #110 in the new NCEES practice Power problems which reads: The only load on a 3 phase 4 wire system is place between Phase B and Phase C. The phase to phase voltage is...
