Re: [Phys-L] youtube the.tragic story of nikola Tesla

No, I just need to understand why more electrical energy can be transmitted when using ac

In this story of Tesla's life it is mentioned that a crucial reason for going with ac for the bulk of electric power transmission is the ability to deliver (I think) twice as much power with pre-existing electric lines.

Could someone please explain how that works.
