Introduction to Circuit Theory Notes
Engineering students are introduced to Circuit Theory subject and its analytical part in their second semester. The students will need to learn the circuit theorems application. Electrical and Electronics Engineering students need to study intensively to become an expert in this subject.
In simple words, circuit theory is a normal flow of electric currents through a metal wire. Usually, the current flows straightforward through the wire. On the other hand, some currents are not associated with electric charges flow. Such currents, which create magnetic fields and electromagnetic waves through empty space, are called Displacement Current.
According to the Principle of Current Continuity, when electric current and displaced current passes through the closed surface at any time is always zero.
Circuit theory is about a network of elements that need to connect a specific device to an energy source. Electrical circuits consist of several circuit elements. Some examples of electrical circuits include communications systems, power systems, and computer systems. Though exact equivalence is nearly impossible to achieve, electrical circuits should represent approximate equivalent circuits with similar intents and behaviour.

FAQs on Circuit Theory Lecture Notes
Question 1.
What is Circuit Theory?
Answer:
Circuit Theory is a mathematical relationship (involving physics numerical) between voltage, resistance, and current. Electric voltage (v) is the energy supply that passes through the conductor, which moves the electrons in the form of an electrical current from one node to another in a circuit. Electrical Current (I) is the movement of electric charges from a negative terminal to the positive terminal for energy supply and positive to negative to ease the current flow. Resistance (R) prevents the electric charge or current flow within a circuit.
Question 2.
Which books can help me improve my grades in the Circuit Theory course?
Answer:
The students should follow the Circuit Theory Textbooks and refer to Circuit Theory Books to prove their merit in the exam. Students will continue to excel if they refer to Circuit Theory Lecture Notes and Circuit Theory Questions and Answers.
