CBSE Class 12 Physics Board Examination 2025: Professional-recommended anticipated questions from Electromagnetic Induction, Alternating Present, and Electromagnetic Waves
The Central Board of Secondary Schooling (CBSE) has launched the date sheet for the Class 10 and 12 Board Exams 2025. For Class 12, the exams will begin on February 15, 2025, and conclude on April 4, 2025. As per the schedule, the Class 12 Physics examination is about for February 21, 2025. With lower than three months to go, college students are intensively making ready for this significant examination.
To help college students in attaining excellence within the Class 12 Physics board examination, Shailendra Pandey, a Physics Wallah college member, has shared an inventory of anticipated questions. College students ought to complement these knowledgeable insights with thorough follow utilizing textbooks, pattern papers, mannequin query papers, and former years’ query papers accessible on CBSE’s official web site.
This text highlights a few of the anticipated questions from key chapters corresponding to Electromagnetic Induction, Alternating Present, and Electromagnetic Waves.

CBSE Board Examination 2025: Preparation suggestions for Class 12 Physics board examination
Create a Research Plan: Divide your research time between principle and numerical (e.g., 40% principle, 60% numerical). Be sure that to allocate time for each day revisions and mock exams to remain on observe and consider your progress usually.
Grasp the Fundamentals: Guarantee a transparent understanding of elementary ideas, formulation, and definitions. Revise key formulation and derivations each day and keep a components sheet for fast reference throughout revision classes.
Follow Numerical: Remedy all solved and unsolved numerical from NCERT, specializing in high-weightage subjects like Present Electrical energy, Electrostatics, Ray and Wave Optics, Magnetic Results of Present, and Alternating Present. Progressively transfer to more durable issues from reference books.
Deal with Necessary Derivations: Memorize and follow step-by-step derivations, as they’re usually requested in exams. Deal with derivations such because the lens maker’s components, electrical discipline because of a dipole, Biot-Savart regulation, and EMF in a rotating coil (AC generator).
Remedy Pattern Papers: Remedy at the very least three pattern papers underneath examination circumstances in the course of the closing month of preparation. Analyze your efficiency to determine weak areas, time administration points, and areas needing additional revision.
Revise Usually: Usually revise theoretical ideas, formulation, and key questions to strengthen your data. Follow numerical and derivations till you are assured and comfy with fixing them within the examination.
