Network Theory Lecture- 35&36

Network Theory Lecture- 35&36:

               In these Lectures i explained about magnetically coupled circuits: in this what is mutual inductance, what is coupling co-efficient, series aiding and series opposing of two mutually connected inductors, parallel aiding and parallel opposing and equivalent circuit for transformer are discussed.and also solved few problems on mutual inductance concept and finally introduced duality principle.
