Define the fundamentals of electrical engineering
The fundamentals of electrical engineering include the fundamental principles of the behavior and handling of electrical energy. They form the basis of several engineering disciplines and provide the necessary foundation for more advanced studies in electronics, power systems and telecommunications.
Key concepts of basic electrical engineering
The fundamentals of electrical engineering include basic principles such as Ohm's law and knowledge of essential circuit components such as resistors, capacitors, and inductors.
Ohm's law and circuit analysis
Ohm's law is the basis of electrical engineering. Understanding the relationship between voltage, current and resistance is essential for analyzing and designing electrical circuits. Here's a breakdown:
Ohm's law formula:
