Detailed Solution
Download Solution PDFThe correct option is 4
Concept:
The following are characteristics of a balanced load.
- All the three-phase has the same impedance in magnitude and phase angle
- All the phases have the same power factor
- Current through the neutral In is zero.
Application:
Ia = 20∠0°, Ib = 20∠(-120°), Ic = 20∠(120°)
In = Ia + Ib + Ic
= 0 A
The current in the neutral wire will be 0 A
