NCERT Free Online Physics Classes: The National Council of Educational Research and Training (NCERT) has launched a free online Physics course for Class 12 students on the SWAYAM portal. The course is designed to help learners build a strong conceptual understanding of Physics through lectures, e-text, problem-solving methods, animations, practice questions, and assignments.
Physics is often considered a challenging subject, but effective teaching combined with hands-on experiments can make it easier to grasp. The NCERT course aims to bridge learning gaps and provide affordable access to quality education. By connecting theory with real-life applications and practical experiments, students can develop sharper problem-solving skills and a deeper understanding of natural principles.
Course Details
The course is divided into two parts (Course 03 and Course 04), covering a wide range of Class 12 Physics topics:
Course 03 Modules (Units 1-5)
- Electrostatics - Electric charges, fields, dipoles, Gauss's law, capacitance
- Current Electricity - Drift velocity, resistance, resistivity, Kirchhoff's rules, electrical energy and power
- Magnetic Effects of Current and Magnetism - Biot-Savart law, cyclotron, Earth's magnetism, galvanometer
- Electromagnetic Induction and Alternating Current - Lenz's law, eddy currents, AC circuits, transformers, power transmission
- Electromagnetic Waves - Maxwell's equations, spectrum, and applications
Course 04 Modules (Units 6-10)
- Optics - Reflection, refraction, prisms, wave optics, interference, diffraction, polarisation
- Dual Nature of Radiation and Matter - Photoelectric effect, Einstein's equation, de Broglie waves
- Atoms and Nuclei - Atomic models, Bohr's theory, radioactivity, nuclear energy
- Electronic Devices - Semiconductors, diodes, transistors, amplifiers, digital electronics
- Communication Systems - Modulation, propagation of waves, modern-day communication
- Both courses together consist of 10 units spread across 43 modules, each supplemented with extra reading material and a final assessment.
