Description

Transformers is an exam-focused electrical engineering programme designed for electrical engineering students targeting university exams and GATE-style practice (all levels). Lessons are paced for semester revision and competitive practice, with clear explanations you can replay anytime.

You will strengthen circuit intuition and numerical methods for Transformers, with diagrams and steps that match how examiners expect answers. Syllabus highlights include Basics of Transformers, Operation of Transformer, Losses In Transformers, Tests on Transformer & Rating, Efficiency and Regulation, Three Phase Transformers, and Auto Transformers. Across 47 lessons, you will move from foundations to problem-solving patterns that show up in university papers and placement tests.

Taught by DAKALA SREENIVASULU, this course keeps theory short and practice heavy—so you can revise faster, spot examiner cues, and build confidence before mocks and finals.
