Popularity of Electrical
Engineering as an optional subject
The following are the suggested books / references that the students can consult
while preparing for Electrical Engineering - Main Examination - Paper I and
Electrical Engineering is best fit as an optional for students who are passionate
about the subject.
Since this is logical subject, scoring is quite straightforward and rote-learning
is not required.
Engineering Electrical Engineering Students can score very well in this subject
as only standard models of sums are asked in the question papers.
Suggestions for Preparation of Electrical Engineering Optional Subject
The following are simple preparation tips to score well in the Electrical Engineering
- Main Examination - Paper I and Paper II.
Prepare selective topics and be thorough in these topics.
For Electrical Engg. People, Circuit Theory,Control Systems,E.M Theory,Energy Conversion,Measurements,Power
Electronics and Power Systems are very easy to prepare,So concentrate on these topics
to score very weill.
Similarly,for Electronics Engg. People, Circuit Theory,Control Systems,E.M Theory,Analog
Elctronics,Digital Electronics,Microprocessor,Analog communication and Digital Communication,Measurements
are very easy to prepare,So concentrate on these topics to score very weill.
Solve problems from previous years questions papers as the same models of the sums
normally repeat every year.
Solve each problem highlighting each step while arriving at the solution. Do not
skip any step thinking it is trivial.
Concentrate on the solved examples from Reference books suggested for the UPSC exam.
Monitor your speed during practice and try to improve it. Lack of time is the main
challenge in this paper, as the solution of each problem will take considerable
amount of time, practicing mock tests is far important than preparation.
