Finding difficult in preparing entire 05 units of EE6504 - Electrical Machines-II subject? Want to get atleast pass marks in Anna University Examinations, you should then study the answers for these important questions. Those who want to boost up their marks can also use these questions. However no guarantee will be given that these questions appear in upcoming examinations. It is only prepared based on experience happened in the past for Anna University Examinations. Read more!

EE6504 - Electrical Machines-II
Nov / Dec 2015 Important Questions
(Regulation 2013)
Note : (To be studied in the same order from 1 to 28 + problems, or atleast first 20 questions & problems for getting minimum pass. There is no guarantee that you will get pass mark by studying these questions. This is for students who find it difficult to study the entire syllabus, and they can study atleast these questions there may be a possibility to pass. Others should study the entire syllabus OR first study these questions, and then study the remaining. STUDY IN THE SAME SERIAL NUMBER ORDER GIVEN. DON’T SHUFFLE)
