A step-down delta-star transformer, with per-phase turns ration of 5, is fed from a 3-phase, 1100 V, 50 Hz source. The secondary of this transformer through a 3-pulse type rectifier feeds a R load of 10 Ω. Find the maximum value of the load current (phase).
A. √2 x 22 A
B. 1 x 11 A
C. √2 x 11 A
D. 1 x 22 A
