A balanced (positive sequence) three-phase AC voltage source is connected to a balanced, star connected load through a star-delta transformer as shown in the figure. The line-to-line voltage rating is 230 V on the star side, and 115 V on the delta side. If the magnetizing current is neglected and Is = 100∠0°A, then what is the value of Ip in Ampere?
A
50∠30°
B
50∠-30°
C
50√3∠30°
D
200∠30°

Correct : a
