Flashcards for CBSE Class 12 Physics (code 042), following the Curriculum 2026-27, split into the nine numbered units in order and then by chapter, plus a Practicals subdeck covering the listed experiments: what each measures, the method, the graph and sources of error. Delete or suspend any subdeck your course leaves out once the deck is yours.

Adding it gives you your own copy, with every subdeck below. Each card then comes back just before you would forget it, and every one you get right or wrong counts towards your mastery of its topic. You can delete or suspend the parts you are not studying once it is yours.

Some of its cards

  • In the experiment to find the focal length of a concave mirror, what is measured for each object position?
    The object distance and the corresponding image distance, found by moving a screen until a sharp image forms
  • What two types of particle make up an atomic nucleus?
    Protons and neutrons
  • What did Oersted's experiment demonstrate?
    That an electric current produces a magnetic field, shown by a compass needle near a current-carrying wire being deflected
  • What problem with Ampere's circuital law did Maxwell identify, that led him to propose displacement current?
    It gave an inconsistent result for a charging capacitor: applied to different surfaces bounded by the same loop, it predicted different enclosed currents, since no conduction current flows between the plates
  • What is electromagnetic induction?
    The production of an induced emf (and current, if the circuit is closed) in a conductor due to a changing magnetic flux linked with it
  • In the Cartesian sign convention used for mirrors and lenses, where is the pole (or optical centre) taken as the origin for measuring distances?
    At the pole of the mirror, or the optical centre of the lens
  • What is an alternating current?
    A current whose magnitude changes continuously with time and whose direction reverses periodically
  • What is the electromotive force (emf) of a cell?
    The potential difference across the terminals of the cell when no current is drawn from it (the open-circuit terminal voltage)
  • What is a wavefront?
    A surface joining all the points in a wave that are in the same phase of oscillation
  • What two poles does every bar magnet have?
    A north pole and a south pole
