That is one simple question that can't have any simple answers! For a start, do you mean "the history of electrical outlet changes" just for one country (such as USA or England, or Australia, or ...) or do you mean worldwide? One way for you to get some answers to this question would be to go to a science museum and ask if there is a section dealing with the history and development of electricity supply systems. Or you could go to your local library and ask one of the staff there to suggest some books for you to read that cover this subject!
