CBSE UGC NET ELECTRONIC SCIENCE

Electronics means the devices including active (amplifying) electrical components. Electronics deals with electrical circuits that involve active electrical components such as vacuum tubes, transistors, diodes and integrated circuits, and associated passive interconnection technologies. Commonly, electronic devices contain circuitry consisting primarily or exclusively of active semiconductors supplemented with passive elements; such a circuit is described as an electronic circuit. The nonlinear behaviour of active components and their ability to control electron flows makes amplification of weak signals possible and electronics is widely used in information processing, telecommunication, and signal processing. The ability of electronic devices to act as switches makes digital information processing possible. Interconnection technologies such as circuit boards, electronics packaging technology, and other varied forms of communication infrastructure complete circuit functionality and transform the mixed components into a regular working system.

 

Question Pattern: There will be two question papers – UGC NET Examination in Electronic Science, Paper II and Paper III. Paper II will have 100 marks in total whereas Paper III will have 150 marks in total. Paper II will cover fifty (50) objective type questions, whereas the Paper III will have seventy five (75) objective type questions, each question carrying two (2) marks. All questions are compulsory in both the papers. The objective type questions will include multiple choices, matching type, true / false and assertion-reasoning type.

Coaching for CBSE UGC NET Exams

It is very essential for any candidate to take proper coaching before attempting to give UGC NET exams. Proper Coaching gives you an idea as to how Questions are going to appear in the UGC NET exams and what are the right answers. Sometimes, it happens by chance that the same kind of question gets repeated again and you are able to score. The preparation for the UGC NET exam & JRF should ideally start 6 months before the exam and the student should attempt to, if not more, at least 2000 questions per subject of the previous year papers. Students should join ASTRAL EDUCATION, Gurgaon, for a world class coaching for UGC NET exams & JRF. ASTRAL is India’s Number One coaching Institute for UGC NET exams coaching. ASTRAL has 95% success rate in exams and 99.99% of students acknowledge this fact till date.

They simply have to register to the Online course, they would be given a user id and a password, and they could login and take the advantage of how ASTRAL really coach. All you need to have is a computer or a laptop, an Internet connection with high speed, with a valid SKYPE id, you would be in a position to take the online classes, without any compromises on the quality of the teaching- you will only benefit. The online coaching would be the same as that provided in the class, the only thing missing would be the real time chat with the faculty. No problem- you could always post the query, and your question would be answered very soon.

The advantage of Online coaching is that you really do not have to move out of your comfort zone and travel all the distance from a city. However, the only disadvantage is that you know nobody and you cannot interact with the faculty directly. But nevertheless, your queries do get answered. And yes, don’t worry about the course material. It gets dispatched to your address soon. So you have both the advantage of getting coached online and you have the material to study and see and report what has not been covered or what is not clear.
