How to pass EDC - Electric circuits and Electron Devices exam - EC2151 Anna University Second Semester - Ref. Electric Circuits Mahmood Nahvi - Joseph A Edminister Schaums outlines - Electronic Devices and Circuits - S Salivahanan pdfs

Let's have a brief overview on the vital areas to be covered in Electron Devices & Circuits - EDC,this might save your head.
EDC is sort of a vague subject.If you have good internals in EDC it won't be a matter to pass this subject.According to UNIT wise split up this is how the important topics,to my knowledge,can be asked as questions in the exams.
