Hi all,
Okay looking at problems 134 and 135. I was able to solve these easy enough. My question...is there a reason why they solved it two different approaches in the Solutions?
Understanding leading, lagging, power triangle. neg vs pos, I used the general few formulas...
P=(V)(I)(pf) ....in 135 P was given
Qold=P (sin Theta old)
Qnew=P(sin Theta new)
Qadd=Qnew-Qold
instead of the SqRt of the Sum of the Squares.
I know there is more than one way to skin a cat, and I understand both approaches. Just wondering if there is a time (general rule) one is better used than the other? I may still discover it, but any input as always is appreciated.
John
