If you are downloading a Quantum PDF for EM-1, ensure it covers the following five units as per AKTU (or similar UPTU syllabus):
Simply downloading the PDF will not guarantee passing marks. Here is a tactical study plan: electrical machines 1 quantum pdf
[ \eta = \frac\textOutput Power\textOutput Power + \textCore Loss + \textCopper Loss ] If you are downloading a Quantum PDF for
(Note: Some syllabi include 3-phase Induction Motors in "Electrical Machines 1", while others reserve it for Part 2. Check your specific syllabus.) The resistance of the armature is 0
Question: A 250V DC shunt motor takes a current of 5A on no-load and 50A on full-load. The resistance of the armature is 0.2Ω and shunt field resistance is 250Ω. Calculate the full-load efficiency.
Solution (as per Quantum approach):
While the Quantum summarizes theory, it often skips derivations. For example, when studying the EMF equation of a transformer, use a standard textbook (like P.S. Bimbhra or I.J. Nagrath) for the derivation, then use the Quantum to memorize the final formula and typical exam questions.
