To
The Principals of affiliated Engineering Colleges having BME Branch.
Sir,
Sub:
JNT University, Hyderabad – Academic & Planning – Corrected syllabus
of “Fundamentals of Electrical Engineering (code 53030)” for B.Tech
BME. (R09 II-I Sem.) also – Reg.
***
It is informed that the corrections are incorporated in the subject of
“Fundamentals of Electrical Engineering (code 53030)” (R09 II/I semester) and 7 units
syllabus is changed into 8 units. The modifications shall be applicable to all courses /
branches of Engineering having this subject, like EIE, ICE, ECM, BME branches etc.
Hence all Principals are requested to instruct their faculty to implement these
modifications with immediate effect from the present semester itself.
Yours faithfully,
Sd/REGISTRAR

UNIT – II
Magnetic Circuits
Magnetic Circuits – Faraday’s laws of electromagnetic induction – concept of self and mutual inductance –
dot convention – coefficient of coupling – composite magnetic circuit - Analysis of series and parallel
magnetic circuits.
UNIT – III
