NCERT Offers Free Online Physics Classes For Class 12 Students, Check The Details

NEW DELHI: 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 the students 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.
