Hi everyone,
I'm taking an electrical course at the university and the professor asks us a very tough question: "Why we use single-phase for power supply while 3-phase is much safer, more efficient? What happens if we replace all the single-phase power supply by the 3-phase one?"
So, why normally household power supply must be single-phase?
All the search on Google so far doesn't satisfy me enough because it cannot give me the benefits in terms of power or technology. So, I hope that someone here can really enlight me .
Thank you so much.
