What is Network Theory?
Electronics and Communication Engineering – Network Theory
Network theory in engineering is the study of how electrical and electronic circuits and systems are interconnected and how they function. It is one of the basic subjects in circuital engineering branches (electrical engineering, electronics engineering) that involves the analysis of electrical networks that consist of interconnected components like resistors, capacitors, inductors, voltage sources, current sources, etc.
Network theory provides the fundamental concepts required for understanding and designing electrical and electronic circuits and systems.
It is very important to have a good understanding of network theory in order to learn the other subjects of electrical engineering and electronics engineering easily. A good understanding of network theory would help to easily grasp concepts in other subjects such as analog electronics, power electronics, electrical machines, power systems, electromagnetic theory, etc.
The ultimate goal of network theory is to understand and predict the behavior of various circuits and elements under various conditions. Network theory also helps in determining other parameters such as power, energy, voltage, current, heat, etc. in any circuit.

FAQs:
1. What is dependent source and independent source?
Ans. The element for which either the voltage or current depend upon a current or voltage elsewhere in the circuit; such elements are called a dependent source.
If the terminal voltage is completely independent of current, or the current is completely independent of voltage, then the element is called an independent source.
2. What is capacitor in Electronics?
Ans. A capacitor is a passive element designed to store energy in its electric field.
3. What is an inductor in Electronics?
Ans. An inductor is a passive two-terminal electrical component that stores energy in a magnetic field when electric current flows through it. An inductor typically consists of an insulated wire wound into a coil.
4. What is a resistor in Electronics?
Ans. Resistor is an element which opposes the flow of charge.
