Why do we use 2 phase instead of 3 phase?

It is used in almost all the countries to transmit power however single phase circuit is used to utilise it in domestic area. Three phase also reduce the conductor size in transmission because if there are two phases current in them may be high in each conductor there fore conductor should have more cross section.

Correspondingly, what is the difference between 2 phase & 3 phase?

Three-phase electric power requires less conductor mass for the same voltage and overall power, compared with a two-phase four-wire circuit of the same carrying capacity. It has replaced two-phase power for commercial distribution of electrical energy, but two-phase circuits are still found in certain control systems.

what is the advantage of three phase system? Advantages of three phase system:For transmission of electrical power three phase supply requires less copper or less conducting material than that of single phase system for given volt-amperes and voltage ratings. Hence 3 phase system is more economical compared to single phase system.

Accordingly, why do we use three phase instead of single phase?

A threephase system is generally more economical than others because it uses less conductor material to transmit electric power than equivalent singlephase or two-phase systems at the same voltage.

What are the 3 phases of electricity?

ThreePhase LoadsAn electrical system is comprised of three main parts: energy generation, energy transmission and energy consumers. The consumers are the loads connected to the electrical system. One of the advantages of a threephase system is that it can supply both single-phase and threephase loads.
