Alternating Current is a key chapter in Physics that explains the flow of electric charge that periodically reverses direction. It covers concepts such as AC voltage and current, root mean square (RMS) values, reactance, impedance, phase difference, resonance in AC circuits, and power in AC circuits, helping students understand how alternating current behaves in practical electrical systems. Mastery of this topic allows students to solve numerical problems, analyze AC circuits, and apply alternating current principles effectively in exams. At PLS Academy, Alternating Current is taught in a clear, exam-oriented manner, focusing on MCQs, past paper trends, and problem-solving techniques, enabling aspirants to excel in MDCAT, ECAT, NUST, and FSC board exams.
