About the course

Electric Circuits is one of the most important and high-scoring topics in Class 12 Physics, forming a critical part of the CBSE syllabus and a frequent focus area in competitive exams like JEE Main, JEE Advanced, and NEET. A strong grasp of this topic is essential not only for excelling in your board exams but also for building the foundation needed for engineering and medical entrance success.

Dr. Balaji Sampath, a renowned educator, has crafted this course by simplifying complex concepts like current, resistance, electromotive force, Kirchhoff’s laws, and circuit analysis through easy-to-understand explanations, vivid animations, and practical examples. This course empowers students to develop a deep understanding, making even the toughest problems approachable and solvable with confidence.

Why this course?

Many students find Electric Circuits challenging due to the abstract concepts and multi-step problem-solving involved. Questions on current flow, resistors in series and parallel, Kirchhoff’s laws, and circuit theorems often consume valuable exam time and cause confusion.

This course, designed by Dr. Balaji Sampath, addresses these challenges by breaking down complex theories into simple, understandable concepts. It includes unique shortcuts, step-by-step solutions, and smart strategies that make solving Electric Circuits problems faster and more accurate — crucial for maximizing scores in JEE, NEET, and CBSE board exams.

What does the course contain?

This micro-course by Dr. Balaji Sampath includes 38 concept lectures and 81 video solutions, designed to help you master Electric Circuits in just 14 hours. With clear explanations, engaging visuals, and practical examples, complex circuit concepts become straightforward. Perfect for JEE and NEET aspirants, the course offers a range of practice problems from basic to advanced levels, along with expert strategies and shortcuts to enhance your problem-solving speed, accuracy, and confidence in exams.
