Assume line voltage "" as reference and include the 30-degree phase shift. A three-phase source, 3-wire, 4160, negative sequence is loaded with the following single-phase loads:

= 5∠53.13°
c = 10∠53.13°
c = 10∠53.13°
= 10∠53.13°
= 5∠53.13°
c = 5∠53.13°

Determine:

a. the overall power factor;
b. the total line a positive sequence;
c. the total line negative sequence;
d. the total line c zero sequence;
e. the neutral current.
