Course details

This course is designed to build a strong foundation in electrical and AC circuit fundamentals for students and job-oriented exam aspirants. It starts with basic electrical concepts such as voltage, current, EMF, and electrical networks, helping learners understand how circuits work from the ground up. The course explains AC fundamentals including RMS value, average value, form factor, frequency, and phase in a simple manner. Learners will understand active, reactive, and apparent power and their importance in real electrical systems. Detailed coverage of AC circuits with resistor, inductor, and capacitor explains why current leads or lags voltage. The course includes RL, RC, and RLC circuits, along with resonance concepts. Kirchhoff’s laws (KCL & KVL) and problem-solving techniques are explained step by step. Important network theorems such as Superposition, Thevenin’s, Norton’s, and Maximum Power Transfer are covered with clear conditions and applications. Concepts of ideal and practical voltage and current sources are also included. The course focuses on numerical problems, MCQs, and exam-oriented questions, making it highly useful for competitive exams and practical understanding.
