BSEH SS Physics case studies
BSEH SS Physics · Put your knowledge to work in context.
The BSEH Senior Secondary Physics examination is the Class 12 physics board assessment conducted by the Board of School Education Haryana. It is intended for students enrolled in Haryana senior secondary schools who need a Class 12 physics credential for higher education, professional courses, or employment. The syllabus spans electrostatics, current electricity, magnetism, electromagnetic induction and alternating currents, electromagnetic waves, optics, dual nature of matter and radiation, atoms and nuclei, electronic devices, experimental skills, mathematical problem solving, and general physics applications. The paper typically combines multiple-choice, short-answer, and long-answer questions, with a strong emphasis on numerical problems and derivations. The BSEH SS Physics case studies are 5 cases and about 2,309 words.
1Dielectric slab on a disconnected capacitor
To demonstrate dielectric effects, a parallel-plate capacitor is built from two circular plates of diameter 12.0 cm separated by 4.0 mm. A student charges the capacitor from a 200 V supply, disconnects the supply, and reads 200 V on an electrometer.
510 words, about 3 min2Potentiometer internal-resistance discrepancy
A student uses a potentiometer with a 2.00 V driver cell and a uniform 10.00 m resistance wire. With the unknown dry cell on open circuit, the balance point is at 6.00 m.
