#### Level of Course Unit

First Cycle Programmes (Bachelor's Degree)

#### Course Coordinator

ASISTANT PROFESSOR SERKAN GÜNEL

#### Offered to

Electrical and Electronics Engineering

#### Course Objective

The objective of the course is to introduce basic circuit theory by presenting basic circuit elements, circuit modeling and analysis techniques. In this respect, Current and voltage law's of Kirchoff, Telegen's theorem, Thevenin ve Norton theorems will be given. Node voltage, Mesh Current, Loop Voltage and Cutset Current Methods will be inspected in detail. Two port circuit analysis will follow. Analysis techniques introduced will be applied to analysis of 2-port circuits. Analysis of circuit containing an active gain block and operational amplifiers will be studied. Finally dynamical circuit elements (capacitor, inductor and mutual inductance) will be introduced.
