The Central Board of Secondary Education (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 assist college students in reaching excellence within the Class 12 Physics board examination, Shailendra Pandey, a Physics Wallah college member, has shared an inventory of expected questions. Students ought to complement these professional insights with thorough follow utilizing textbooks, pattern papers, mannequin query papers, and earlier years’ query papers obtainable on CBSE’s official web site.
This article highlights a number of the anticipated questions from key chapters equivalent to Electromagnetic Induction, Alternating Current, and Electromagnetic Waves.
CBSE Class 12 Physics Board Exam: Expected questions from Electromagnetic Induction, Alternating Current, and Electromagnetic Waves
Chapter 6: Electromagnetic Induction
Question 1: State Faraday’s legal guidelines of electromagnetic induction. Derive the expression for induced EMF.
Question 2: Explain Lenz’s legislation and its functions.
Question 3: Derive the expression for mutual inductance of two solenoids.
Question 4: Derive the expression for the self-inductance of a solenoid.
Question 5: Explain the working of an AC generator.
Chapter 7: Alternating Current
Question 1: Derive the expression for the impedance in an LCR sequence circuit.
Question 2: Explain the idea of resonance in an LCR circuit.
Question 3: Draw the phasor diagram for an LCR circuit.
Question 4: Explain the ability issue and its significance in AC circuits.
Chapter 8: Electromagnetic Waves

Question 2: State Maxwell’s equations and clarify their bodily significance.
Question 3: Write the mathematical expression for a aircraft electromagnetic wave propagating in house.
CBSE Board Exam 2025: Preparation ideas for Class 12 Physics board examination
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 exams to remain on monitor and consider your progress repeatedly.
Master the Basics: Ensure a transparent understanding of basic ideas, formulation, and definitions. Revise key formulation and derivations day by day and keep a formulation 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 more durable issues from reference books.
Focus on Important Derivations: Memorize and follow step-by-step derivations, as they’re typically requested in exams. Focus on derivations such because the lens maker’s formulation, electrical area as a consequence of a dipole, Biot-Savart legislation, and EMF in a rotating coil (AC generator).
Solve Sample Papers: Solve no less than three pattern papers beneath examination circumstances throughout the ultimate month of preparation. Analyze your efficiency to establish 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.
