Alternating current 12 th class cbse

This course provides a comprehensive understanding of Alternating Current (AC), a fundamental topic in Class 12 Physics. Students will explore the behavior of current and voltage in AC circuits, focusing on the analysis of resistance (R), inductance (L), and capacitance (C) in series and parallel combinations. The course covers phasor diagrams, impedance, reactance, and the concept of resonance in LCR circuits. Learners will also study the power factor, rms and peak values, and energy transfer in AC circuits. Practical applications such as transformers, household AC supply, and power transmission are explained to link theory with real-world systems. Through conceptual discussions, numerical problems, and experiments, students will gain clarity and problem-solving skills essential for board exams and competitive tests like JEE and NEET. This course strengthens both conceptual understanding and practical insight into alternating current phenomena. It is my proshnto all the student who join this course that you all going to enjoy the class to the fullest.
