GATE 2013 EEE Question Paper Analysis  SET A,SET B,SET C,SET D
Overall Paper Snapshot
The GATE 2013 question paper for electrical students has followed similar pattern as the GATE 2012, with the weightage for the subjects was almost same as GATE 2012. The questions in the core areas required lot of analysis. It is not just the design of the question, but the options were also carefully designed to confuse the students. Most of the options for a question were very similar, so the students have to completely solve the question to get the right option. Most of the students thought that the question paper was very easy during the exam because they could answer many questions. But their feeling is quite opposite after knowing the right answers due to the above mentioned reasons. Similar to GATE 2012, most of the questions from common topics to ECE /EE like Networks, Signals & Systems, Control Systems, Analog and Digital Electronics were same. But the engineering mathematics questions were different for EE and EC students this year.

Electric Circuits and Fields: The weightage for the subject is less when compared to the last year. It has a weightage of 12 marks (17 marks last year). The questions were more from fundamentals, and hence, though they look difficult but normal approach is enough to solve the problems.
While solving the 1 mark question asked from special case of maximum power transfer theorem is given, students usually study that the source impedance must be equal to load impedance for the maximum power to be transferred to the load, but when the load is just a resistance then the value of the resistance is equal to the absolute value of the source impedance.
For the 1 mark question from star delta transformation, students usually think that the impedance will decrease when resistance are converted from star to delta, its true but to mislead the students the question was asked about the scaling factor which will remain same even after the conversion.
The 2 Other one mark questions given needed proper analysis before we answer it. Otherwise there was a great possibility to go with the wrong option.
For the 2 mark question from thevenin’s theorem was given with dependent source, students feel uneasy when there are dependent sources in the thevenin’s theorem problems. But this problem is very simple if you know the procedure.
2 marks were asked from the areas like basics of capacitance and Qfactor calculation were given which are difficult and can be solved only if the students are strong at basics.
Signals and systems: Signals and systems had a weightage of 4 marks  two 1Mark questions and one 2 Mark question. These questions were also based on simple concepts like periodicity, nyquist sampling theorem, impulse response of the system.
Electrical Machines: had very less weightage of 6 Marks when compared with previous years.
Electrical students always usually expect a lot of questions on this subject, but from the last year the weightage of the subject has gone down

There were two 1 mark questions and these are easy and moderate. Question on transformer was analytical.

There were two 2 mark question and these two were of difficult level. Concept seems to be easy but the solutions need lot of analysis to get the right answer.
Power systems: Power systems had the same weightage of 8 marks as the previous year. Most of the questions were of higher difficulty level. One mark question on load angle was very easy, while the One mark question on active power and reactive power was tricky and confusing. Two mark question on capacitor current required analytical approach and the options are confusing. Linked answer question on load angles and real power calculation was of higher difficulty level.
Control system: It had the highest weightage of 14 marks when compared with last year’s 11 marks. But the most of the problems were from easy or moderate category. Even an average student can easily score 10 marks from the control systems.

1 mark questions on basic concepts like transfer function, stability, step response were given.
 Simple 1 mark question on bode plot was given.
 2 mark question on signal flow graph was a direct question.
 2 mark question on time constant of first order system was of moderate level.
 Common data question from state space analysis was very basic.
Electrical and Electronic Measurements: Had a weightage of 4 marks. There were two one mark questions and one two mark question.
 One mark question PMMC voltmeter and voltmeter reading were thoroughly analytical, student must be strong in basics to answer this question.
 Two marks question on bridge circuit was analytical and of difficult level.
Analog and Digital Electronics: Analog and Digital Electronics had a weightage of 13 Marks this year, in which 8 Marks from Analog part, and remaining 5 marks from digital circuits. The questions on ADE mainly test the basic understanding of the working of the diode, BJT, and OpAmp.
Understanding of concepts like, how the transistor works when base and collector are at same potential, How the Rin and Rout of the feedback circuit change with different modes of connections, Gain of Opamp circuit both in inverting and noninverting modes of operation, applying KCL for zener diode would be of great help to the students. By using such simple formulae, one can answer analog circuit questions.
In Digital circuits, the circuit may look complex, but if the candidate knows the working of basic gates and flip flops, he/she can answer it in seconds. The questions from analog and digital electronics were not difficult, but they test the understanding of basic concepts.
Power Electronics and Drives: Had more weightage of 12 Marks when compared with last year weightage of 8 marks. All the questions were of moderate and difficult level.
 Question on conduction time of Thyristor and chopper drive were basic but analytical.
 Common data and linked answer questions were of high standard. Only those who are strong in power electronics can answer these questions.

In Engineering Mathematics, questions are given from the areas linear algebra, Calculus, Complex variables, probability and numerical methods. Most of the questions are simple and can be solved by the direct application of the standard results. For few questions, analytical ability is required to answer, because the options given are very close. As a whole, the questions are moderately tough when compared to previous years.
General Aptitude
In the General Aptitude section of GATE 2013 the weightage given to verbal ability and numericlal ability were 6 Marks and 9 marks respectively.The level of difficulty of questions varied from easy to moderate with no difficult questions. A student can score 12 marks out of 15 Marks in this section without facing great challenge. The section thus provided much needed avenues to score as the students were choked for marks in their branch of engineering.The questions on verbal ability were on sentence completion, grammar, Antonmys/synonyms and Critical reasoning.Where as questions on numerical ability involved questions on basic Arithmetic like Time and Distance,Time and work,Progressions and Probability.
