Ask AI: Hsc 2025 mh board 12th physics 100% sure expected physics question

It's important to remember that no list can guarantee specific questions on an exam, as they can vary from year to year. However, I can give you a list of important topics and types of questions that frequently appear in the Maharashtra HSC 12th Physics exam. This might help you focus your studies effectively. 1. **Electrostatics:** - Coulomb's law, electric field, and potential - Capacitance and capacitors 2. **Current Electricity:** - Ohm's law, Kirchhoff's laws, and their applications - Electrical circuits, series and parallel combinations of resistors, Wheatstone bridge 3. **Magnetic Effects of Electric Current:** - Biot-Savart law and Ampere's circuital law - Magnetic field due to current-carrying conductor, force on a moving charge in a magnetic field (Lorentz force), and the force between two parallel current-carrying conductors 4. **Electromagnetic Induction and Alternating Currents:** - Faraday's laws of electromagnetic induction, Lenz's law, and self and mutual inductance - AC circuits, LC oscillations, transformers 5. **Optics:** - Wave optics: Interference, diffraction, Young's double slit experiment - Ray optics: Reflection and refraction, lens formula, mirror formula, and magnification 6. **Dual Nature of Radiation and Matter:** - Photoelectric effect, Einstein’s photoelectric equation - Matter waves and de-Broglie hypothesis 7. **Atoms and Nuclei:** - Bohr's model, energy levels, and hydrogen spectrum - Radioactivity, alpha, beta, and gamma decay, and half-life 8. **Electronic Devices:** - Semiconductors, PN junction, diodes, and transistors - Logic gates and their combinations 9. **Communication Systems:** - Principles of communication, types of modulation, and bandwidth of signals Here are some types of questions that could appear: - Definition-based questions: Define electric flux, capacitance, etc. - Derivations: Derive expressions for capacitance of a parallel plate capacitor, potential due to a point charge, etc. - Numerical problems: Problems based on Ohm's law, Kirchhoff's laws, magnetic effects, etc. - Conceptual questions: Explain the working of a transistor, the Doppler effect in light, etc. - Short answer: Describe the photoelectric effect, uses of a transformer, etc. To maximize your preparation, it’s a good idea to: 1. Solve previous years' question papers. 2. Practice with sample papers and mock tests. 3. Understand the concepts thoroughly rather than rote memorizing. 4. Focus on doing well in practicals/internal assessment components as they can boost your overall percentage. Make sure you thoroughly review your textbook and any supplementary material provided by your teacher or school. Good luck with your preparation!
