Hello, All! This is a thread that should address my questions and evolve into a general discussion on AC and DC for the purpose of interest. My first question is: What did Nikola Tesla add to the field of electronics and AC? I've read all over the web two conflicting ideas 1) Tesla is God, Edison is the Devil and 2) Tesla added little to an already rich field. To what degree, if any, are either of these two ideas correct? My second question is: How are AC and DC used in today's modern society and was there a 'winner' to the current wars? While my knowledge is limited in the field, which shows through the way in which I am asking the questions, answers in full detail would be appreciated.
