CBSE Class 12 Physics Board Examination 2025: Knowledgeable-recommended anticipated questions from Atoms, Nuclei, and Semiconductor Electronics
The Central Board of Secondary Schooling (CBSE) has launched the date sheet for the Class 10 and 12 Board Exams 2025. For Class 12 college students, exams will start on February 15, 2025, and conclude on April 4, 2025. In keeping with the schedule, the Class 12 Physics examination is slated for February 21, 2025. With lower than three months left, college students are intensively making ready to excel on this important topic.
To help of their preparation, Shailendra Pandey, a school member at Physics Wallah, has curated a listing of anticipated questions for the Class 12 Physics Board Examination 2025. Whereas these knowledgeable insights are useful, college students are additionally inspired to deal with textbooks, pattern papers, mannequin query papers, and former years’ papers out there on CBSE’s official web site.
This text highlights a number of the anticipated questions from key chapters like Atoms, Nuclei, and Semiconductor Electronics.
CBSE Board Examination 2025: Anticipated questions from Atoms, Nuclei, and Semiconductor Electronics – Supplies, Units, and Easy Circuits
Chapter 12: Atoms
Query 1: Clarify Rutherford’s mannequin of the atom and its limitations.
Query 2: Derive the expression for the radius of the nth orbit of the hydrogen atom utilizing Bohr’s mannequin.
Query 3: State and derive the expression for the power of an electron within the nth orbit of a hydrogen atom.
Query 4: Clarify the spectral sequence of the hydrogen atom (Lyman, Balmer, and so on.).
Query 5: Numerical: Calculate the wavelength of the emitted photon in the course of the transition of an electron between two power ranges in a hydrogen atom.
Chapter 13: Nuclei
Query 1: Outline mass defect and binding power. Derive the relation between them.
Query 2: Clarify the nuclear pressure and its traits.
Query 3: Clarify nuclear fission and fusion, with their purposes in power manufacturing.
Chapter 14: Semiconductor Electronics – Supplies, Units, and Easy Circuits
Query 1: Clarify the distinction between intrinsic and extrinsic semiconductors.
Query 2: Talk about the working of a p-n junction diode in ahead and reverse bias.
Query 3: Draw and clarify the circuit diagram of a half-wave rectifier.
Query 4: Derive the expression for the effectivity of a full-wave rectifier.
CBSE Board Examination 2025: Preparation ideas for Class 12 Physics board examination
Perceive the Syllabus: Familiarize your self with the newest CBSE syllabus, specializing in chapters with greater weightage like Optics, Electrostatics, and Present Electrical energy. Concentrate on subjects which have been eliminated or modified to streamline your preparation.
Arrange Examine Supplies: Use NCERT textbooks and the NCERT Wallah YouTube Channel (Vijeta Collection) as your major assets. Moreover, consult with supplementary guides like SL Arora for further numerical and maintain CBSE pattern papers and previous years’ query papers useful for observe.
Create a Examine Plan: Divide your examine time between principle and numerical (e.g., 40% principle, 60% numerical). Ensure to allocate time for each day revisions and mock assessments to remain on observe and consider your progress commonly.
Grasp the Fundamentals: Guarantee a transparent understanding of elementary ideas, formulation, and definitions. Revise key formulation and derivations each day and preserve a formulation 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. Step by step transfer to harder issues from reference books.
Deal with Vital Derivations: Memorize and observe step-by-step derivations, as they’re typically requested in exams. Deal with derivations such because the lens maker’s formulation, electrical area as a result of a dipole, Biot-Savart regulation, and EMF in a rotating coil (AC generator).
Remedy Pattern Papers: Remedy no less than three pattern papers below examination situations in the course of the ultimate 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 bolster your information. Follow numerical and derivations till you are assured and cozy with fixing them within the examination.
