Suppose {I}_{ {A}}, {I}_{ {B}} and {I}_{ {C}} are a set of unbalanced current phasors in a three-phase system. The phase {B} zero-sequence current {I}_{ {B} 0}=0.1 ∠ 0^{∘} p.u. If phase {A} current {I}_{ {A}}=1.1 ∠ 0^{∘} p.u. and phase {C} current {I}_{ {C}}=(1

Question

Suppose  {I}_{ {A}},  {I}_{ {B}} and  {I}_{ {C}} are a set of unbalanced current phasors in a three-phase system. The phase  {B} zero-sequence current  {I}_{ {B} 0}=0.1 ∠ 0^{∘} p.u. If phase  {A} current  {I}_{ {A}}=1.1 ∠ 0^{∘} p.u. and phase  {C} current  {I}_{ {C}}=(1<120^{∘}+0.1) p.u., then  {I}_{ {B}} in p.u. is
