BPSC - CCE
This subtopic covers fundamental physics concepts like laws, energy, motion, and electromagnetic phenomena. It is highly relevant for BPSC exams, testing theoretical knowledge and numerical problems.
Key Concepts
Avogadro's Law
Equal volumes of gases under same temp and pressure have same molecules.
Relativity
Einstein's theory explaining space-time and gravity.
Speed of Sound
Maximum in solids, minimum in gases.
Mirror Focal Length
Plane mirror has infinite focal length.
Short Circuit
Excessive current due to low resistance.
Thomson Effect
Heat absorption or evolution in a conductor with temp gradient.
Magnifying Glass
Uses convex lens to converge light.
Paramagnetism
Materials like platinum align with magnetic fields.
Energy Conversion
Solar to ATP in chloroplasts.
Electric Current
Measured by ammeter.
