CBSE Class 12 Physics Board Exam 2025: Expert-recommended expected questions from Electric Charges and Fields, Electrostatic Potential and Capacitance, and Current Electricity – Newz9

The Central Board of Secondary Education (CBSE) has issued the examination date sheet for Class 10 and 12 college students. The CBSE Board Exam 2025 for Class 12 will start on February 15, 2025, and will conclude on April 4, 2025. According to the CBSE Class 12 board examination 2025 date sheet, the Class 12 Physics examination is scheduled for February 21, 2025. With lower than three months remaining, Class 12 college students are rigorously getting ready for the Physics board examination.
To assist college students excel within the Class 12 Physics board examination 2025, Shailendra Pandey, a college member at Physics Wallahhas compiled a set of expected questions. Along with these knowledgeable strategies, it’s important for college kids to completely put together utilizing their textbooks, pattern papers, mannequin query papers, and earlier years’ query papers accessible on CBSE’s official web site.
In this text, we’ll discover a few of the expected questions from Electric Charges and Fields, Electrostatic Potential and Capacitance,and Current Electricity,

CBSE Board Exam 2025: Preparation ideas for Class 12 Physics board examination

Understand the Syllabus: Familiarize your self with the most recent CBSE syllabus, specializing in chapters with increased weightage like Optics, Electrostatics, and Current Electricity. Be conscious of matters which were eliminated or modified to streamline your preparation.
Organize Study Materials: Use NCERT textbooks and the NCERT Wallah YouTube Channel (Vijeta Series) as your main sources. Additionally, consult with supplementary guides like SL Arora for additional numerical and hold CBSE pattern papers and previous years’ query papers helpful for apply.
Create a Study Plan: Divide your examine time between principle and numerical (eg, 40% principle, 60% numerical). Make positive to allocate time for day by day revisions and mock assessments to remain on monitor and consider your progress frequently.
Master the Basics: Ensure a transparent understanding of basic ideas, formulation, and definitions. Revise key formulation and derivations day by day and keep a components sheet for fast reference throughout revision periods.
Practice Numerical: Solve all solved and unsolved numerical from NCERT, specializing in excessive-weightage matters like Current Electricity, Electrostatics, Ray and Wave Optics, Magnetic Effects of Current, and Alternating Current. Gradually transfer to harder issues from reference books.
Focus on Important Derivations: Memorize and apply step-by-step derivations, as they’re typically requested in exams. Focus on derivations such because the lens maker’s components, electrical area as a consequence of a dipole, Biot-Savart legislation, and EMF in a rotating coil (AC generator).
Solve Sample Papers: Solve not less than three pattern papers below examination circumstances through the closing month of preparation. Analyze your efficiency to determine weak areas, time administration points, and areas needing additional revision.
Revise Regularly: Regularly revise theoretical ideas, formulation, and key questions to strengthen your information. Practice numerical and derivations till you are assured and snug with fixing them within the examination.
Use Flashcards: Create flashcards for formulation, models, dimensions, and legal guidelines, making them very best for fast revision of essential ideas. They will enable you to rapidly recall important data earlier than exams.
Take Care of Presentation: Practice drawing neat, labeled diagrams akin to ray and circuit diagrams. When answering, write derivations systematically by beginning with the components, together with correct models in numerical solutions, and boxing the ultimate reply to focus on it.
