Answer:

a) 7.5A

b) 370V

Step-by-step explanation:

Note that the Line current is the current through any one line between a three-phase source and load.

From the given question, The source line current =7.5A(approximately)

While the Source line voltage = 370V.

Kindly go through the attached file for a step by step detail of how I arrived at these answers.
