BSEB Inter Physics study guide
BSEB Inter Physics · Work through your exam, one topic at a time.
The BSEB Intermediate Physics examination is the Class 12 physics paper set by the Bihar School Examination Board, the state board that certifies higher secondary students across Bihar. Candidates take it as part of the Intermediate (Science) stream, usually alongside Chemistry, Mathematics or Biology, and the mark feeds directly into board certification and into eligibility for undergraduate science and engineering admissions. The BSEB Inter Physics study guide has 12 sections and about 3,209 words.
01Electrostatics
Electrostatics is the domain that examines charges at rest: Coulomb force, electric field, potential, Gauss's law, capacitors and dielectric materials. The exam tests definitions plus numerical problems, so keep both formula and physical meaning ready.
266 words, about 1 min02Current Electricity
Current Electricity tests the flow of charge in conductors and circuits: Ohm's law, resistivity, drift velocity, cells, Kirchhoff's rules, Wheatstone bridge and potentiometer. Expect numericals on equivalent resistance and internal resistance.
267 words, about 1 min03Magnetic Effects of Current and Magnetism
Magnetic Effects of Current and Magnetism covers fields produced by currents, forces on moving charges and wires, torque on loops, galvanometers and magnetic materials. The exam often asks direction plus magnitude.
265 words, about 1 min04Electromagnetic Induction and Alternating Current
Electromagnetic Induction and Alternating Current tests changing flux, Lenz's law, self- and mutual inductance, AC circuits with R, L and C, resonance, power factor and transformers. Faraday's law: ε = -N dΦ/dt.
249 words, about 1 min05Electromagnetic Waves and Optics
Electromagnetic Waves and Optics covers displacement current, the EM spectrum, reflection, refraction, lenses and mirrors, interference, diffraction and polarisation. Ray optics numericals and wave-optics reasoning both appear.
273 words, about 1 min06Dual Nature of Matter and Radiation
Dual Nature of Matter and Radiation tests the photoelectric effect, Einstein's photoelectric equation, de Broglie waves and evidence for wave-particle duality. Numerical questions usually involve energy, frequency, wavelength or stopping potential.
247 words, about 1 min07Atoms and Nuclei
Atoms and Nuclei covers Bohr's model, hydrogen spectral series, nuclear size and density, radioactivity, decay law, half-life, binding energy, fission and fusion. The exam favours short derivations and half-life calculations.
263 words, about 1 min08Semiconductor Electronics and Devices
Semiconductor Electronics and Devices tests energy bands, intrinsic and extrinsic semiconductors, p-n junctions, diodes, rectifiers, transistors and logic gates. Questions often combine biasing with current gain.
299 words, about 1 min09Practical Physics and Experimental Skills
Practical Physics and Experimental Skills tests instrument reading, least count, error treatment and standard experiments such as metre bridge, potentiometer, Ohm's law, lens focal length and prism deviation. You must describe the procedure and calculate from readings.
274 words, about 1 min10Mathematical Physics and Problem Solving
Mathematical Physics and Problem Solving tests the mathematics used inside physics: vectors, trigonometry, differentiation, integration, logarithms, dimensional analysis, graphs and significant figures. The goal is to choose the right mathematical tool before substituting numbers.
273 words, about 1 min11Communication Systems and Modern Applications
Communication Systems and Modern Applications covers modulation, bandwidth, antenna length, propagation, optical fibre, satellites, lasers and selected modern devices. The exam tests why modulation is needed and simple bandwidth or wavelength calculations.
253 words, about 1 min12General Physics Concepts and Scientific Reasoning
General Physics Concepts and Scientific Reasoning tests units, dimensions, Newtonian mechanics, work-energy, gravitation, thermodynamics, waves and the logic of experimental conclusions. It rewards clean reasoning across topics rather than a single formula.
