Circuit analysis and design become fundamental principles in the realm of electrical engineering. They entail a systematic methodology to analyze the behavior of electrical circuits and develop new ones that fulfill specific requirements. Fundamental circuit laws, such as Kirchhoff's Regulations, Ohm's Law, and the theory of resistance, form the base of circuit analysis.

These laws regulate the relationships between voltage, current, and resistance in a circuit. Electrical simulation tools play a vital role in modern circuit design, allowing engineers to predict the behavior of circuits before physical construction.

Moreover, the knowledge of various circuit elements, such as resistors, capacitors, and inductors, is necessary for effective circuit design.

Power Electronics and Control Systems

Power electronics deals with the efficient transformation of electrical energy.
