How to Choose Books for the Kerala PSC Sub Engineer Electrical Exam 2026
1: Between the period of 1858-1947, how many Viceroys ruled over India?
Before the lists, keep these rules in mind:
- The exam is diploma level. Kerala PSC questions are mostly based on diploma-level Electrical Engineering, with numericals and fact-based questions. You do not need to read every advanced B.Tech text cover to cover.
- One main book per topic. Pick one standard book for each module and finish it. Use a second book only to clear doubts.
- Use the syllabus as your filter. Read only the chapters named in the detailed syllabus. The syllabus note also says questions from other topics of the educational qualification may appear, so keep your diploma textbooks handy.
- Add objective practice. Textbooks build concepts, but MCQ practice and previous papers build exam speed.
- Check the latest edition. Editions and publishers change, so check availability before buying.
The books below are widely used standard titles for Electrical Engineering. Prices and editions vary, so confirm with the bookseller before buying.
