Every definition needed for CSEC Physics, organised by syllabus section. Covers mechanics, thermal physics, waves and optics, electricity and magnetism, and the physics of the atom.
Key formulas, rules, and results for CSEC Mathematics, organised by topic.
Direct current versus alternating current, AC voltage-time graphs (period, frequency, peak voltage), half-wave rectification using a diode, and comparing DC and rectified AC waveforms.
The development of atomic models from Thomson through Rutherford to Bohr, the Geiger-Marsden gold foil experiment, the nuclide notation and its meaning, isotopes, and the electron shell model.
Electric current (I = Q/t), conductors, insulators, and semiconductors, electron flow versus conventional current, EMF and potential difference, resistance (R = V/I), Ohm's Law, and I-V characteristics.
Parallel wiring of domestic appliances, the purpose of fuses and circuit breakers, how to select the correct fuse rating, the earth wire and its protective function, and the effects of incorrect voltage on appliances.
Series and parallel circuits, equivalent resistance formulas, ammeter and voltmeter placement, circuit analysis, and cells (primary versus secondary).
Electrical power (P = IV = I²R = V²/R), energy (E = Pt), the kilowatt-hour as a unit of energy, efficiency of electrical appliances, and comparing LED, fluorescent, and incandescent lamps.
Properties common to all electromagnetic waves, the full spectrum from gamma to radio waves ordered by frequency and wavelength, sources and uses of each type, and associated hazards.
Magnetic fields around conductors and solenoids, the right-hand grip rule, the relay, force on a current-carrying conductor, Fleming's left-hand rule, the DC motor, electromagnetic induction, the AC generator, and the transformer (turns ratio, efficiency).
