Answer / Vijay Kumar Arya

In a 2-phase system, the phase angle between the two phases is 90 degrees. In contrast, in a 3-phase system, the phase angle between any two phases is approximately 120 degrees (the ideal value for a balanced three-phase system).nPower in a three-phase system is higher than in a two-phase system because more current can be transmitted simultaneously.nCurrent in a three-phase system is also divided among three conductors, reducing the current density and potential for overheating compared to a two-phase system.
