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=50. If the magnetizing current is neglected, and the currents in two windings are I2 = 2∠30° A and I3 = 2∠150° A, then what is the value of the current I1 in Ampere?
A
1∠90°
B
1∠270°
C
4∠90°
D
4∠270°

Correct : a
