I have read many books and search on internet but never able to find the right answer. I hope some one will solve my confusion.
We know that DC never changes it direction so one wire always have maximum potential while other wire always have 0 potential.
There may be two possibility of AC,
1)
On first half cycle one wire is at max potential while other is at 0 potential but on next half cycle the wire which was at max potential will be at 0 potential while other which was at 0 potential will be at max potential as shown in figure below,
2)
On first half cycle one wire will be at positive max potential and on next half cycle this wire will be at negative max potential while the other wire always remain at 0 potential. As shown in figure below,
Can someone explain which concept is correct.
