Circuit analysis and network theory(basic electrical engineering)
The node method or the node voltage method, is a very powerful approach for circuit analysis and it is based on the application of KCL, KVL and Ohm's law. this conatin basic concept and network theory. Network theory is the study of solving the problems of electric circuits or electric networks.this notes covers all the important topics of the chapter.Its helpful for the quick revision for the chapter. This chapter was taught to the students of first year of DELHI TECHNOLOGICAL UNIVERSITY(one of the top engineering colleges of india). thank you :)

Transformers
*state the purpose of a transformer. • explain the principle of mutual induction. · • determine the output voltage of a transformer if the input voltage and turns ratio are known. • determine the full-load current of a transformer given the kVA and voltages of the primary and secondary windings. • identify the common types of transformers from their schematic diagrams. • read transformer winding diagrams and connect a transformer for the desired primary and secondary voltage. • choose the proper transformer taps to obtain the desired output voltage. • connect buck and boost transformers to obtain desired voltage for a single-phase application. • choose the correct transformer kVA for the application, given the voltage, current, and phase requirement of a load. • size overcurrent protection for dry-type transformers operating at 600 V or less. • size the feeder conductor for the transformer and wires from the transformer to loads. • properly ground a transformer, and the secondary electrical system produced by the transformer.
