The currents in a $$ connected load are Iab$=10/0$o $,$ Ibc$=20/-90$o$,$ and Ica$=15/90$o Amps.

Calculate:

a$)$ The sequence components of the $-$load currents, dentoed I$0,$ I$1$ and I$2$

b$)$ The line currents Ia$,$ Ib and Ic$,$ which feed the $-$load

c$)$ The sequence components of the line currents IL$0,$ IL$1,$ and IL$2.$

Hint: The results should reflect the following: Line currents are $3$ times the phase

currents and a shift of $30$ degrees, one forward and one backward. Think about the

zero sequence.
