The bigger questions is, why don't you do your own homework?
Hameedulla,
Do you think you are doing yourself a favor by not studying and understanding electrical theory? Googling answers might help you find them, but unless you familiarize yourself with the material and actually understand it in your head, you are simply memorizing answers and the parrotting them back on exams.
LawnGuyLandSparky,
1- What I am asking, is not homework or classwork. These are the topics which I do by myself.
2- When I am posting a question here, it doest mean that I dont know the answer but I only want to know others explaination regarding question like three winding question. I have got some good comment and explaination by others. I really appreciate those explainations which are difficult to find from books.
3- As long as google search is concerned, I am much familiar that you might not be.
4- By the way let me tell you, that this site is buit for discussion. It is not necessary for you to answer a question if you dont know. Just read and understand others explaination.
5- Regarding to three winding transformer question you had posted some comment and it has been removed by moderator. I hope you to understand this think before posting something. I have also sent you one private message read it.
6- I am engineer, I am not you and I have already studied that much of books that you cant think of that. If you study and work you can ask question. Before pointing out like this, think carefully.
