PLO 1: Engineering Knowledge (High relevance)
This is one of the most important core course that introduces some fundamental concepts regarding
engineering knowledge of electrical machines i.e construction and working principles of various
Transformer, DC and AC machines . The exercises, Quizzes, exams, and lab work require direct application
of mathematics, scientific, and engineering knowledge to successfully complete the course.

PLO 2: Problem Analysis (High relevance)
Application of the fundamental concepts to formulate a solution requires analysis and identification
of key requirements. Therefore, problem analysis is of high relevance to this course used in solving
assignments, quizzes, open-ended Labs, and problem-based learning tasks.
PLO-04: Investigation (High relevance)
An ability to investigate complex engineering problems in a methodical way including literature survey,
design and conduct of experiments, analysis and interpretation of experimental data and synthesis of
information to derive valid conclusions.
PLO-05: Modern Tool Usage (High relevance)
An ability to create, select and apply appropriate techniques, resources and modern engineering and IT
tools, including prediction and modeling to complex engineering activities, with an understanding of the
limitations.
PLO 10: Communication (Average relevance)
In this course, students are required to submit their LAB reports in a well-organized manner. In
particular, students are required to submit and present a comprehensive design report in groups
against a semester project to enhance their written and oral communication skills.
PLO 8, 9 (Low relevance)
These PLOs are not covered in detail here. However certain aspects are covered directly or indirectly.
For example, project management skill is developed during the planning of different stages of the
semester projects.
