Refer to the above diagram Assume voltages and currents in both three-phase AC networks are balanced. Current la is equal to 10 A and it leads voltage Vab by 90 degrees. The magnitude of voltage Vab is equal to 11000 V. (Hint: Draw a phasor diagram) Which one is the correct statement? Select one: O a. All of the other statements are incorrect. O b. The difference between the value on the display labelled "W2" and the value on the display labelled "W1" that is (W2-W1) will be equal to: -11000x10xsin(120 degrees) or 11000x10xcos(150) Oc. The difference between the value on the display labelled "W2" and the value on the display labelled "W1" that is (W2-W1) will be equal to: -11000x10xsin(90 degrees) or 11000x10xcos(180 degrees) O d. The difference between the value on the display labelled "W2" and the value on the display labelled "Ww1" that is (W2-W1) will be equal to zero.
