Introduction Electric Circuit Theory and Electromagnetic field theory are two foundational subject on which Electrical Engineering is supported. To understand core subject like Electrical machines, Power Electronics and Power system one have to good understanding of both Electric circuit Theory and Field theory. So we are going to start our journey in Electrical Engineering by learning Concept related to Electric Circuit Theory. Starting with circuit theory We have clear understanding of terminology used in Circuit theory. So below Some terms are described which we encountered in our path to learning circuit theory. Circuit : The interconnection of Elements which forms closed path for flow of current is called circuit. Network : The interconnection of Elements are called Network. Now by reading this definition we got confused Circuit and Network supposed to be the same thing but there is just small difference between them. I'll explain it through images shown one of them is circuit...
