Question

A three-winding transformer is connected to an AC voltage source as shown in the figure. The number of turns are as follows: N1=100,N2=50,N3=50N_1 = 100, N_2 = 50, N_3 = 50. If the magnetizing current is neglected, and the currents in two windings are Iˉ2=2∠30∘ A\bar{I}_2 = 2 \angle 30^\circ\text{ A} and Iˉ3=2∠150∘ A\bar{I}_3 = 2 \angle 150^\circ\text{ A}, then what is the value of the current Iˉ1\bar{I}_1 in Ampere?
