Physics 3rd secondary

Mastering High School Physics: From Classical Electromagnetism to Quantum Concepts

A comprehensive, results-driven physics course specifically designed for High School (Grade 12 / General Secondary) students. This curriculum bridges fundamental circuit analysis with advanced electromagnetic applications and modern physics, focusing on conceptual clarity, graph analysis, and high-yield problem-solving techniques.

Syllabus & Core Topics

•  Direct Current (DC) Circuits

  • Electric Current & Ohm’s Law: Electric intensity, potential difference, and electric resistance with underlying factor relationships.

  • Ohm’s Law for Closed Circuits: Battery electromotive force (EMF), internal resistance, and circuit potential analysis.

  • Kirchhoff’s Laws: First (current) and second (voltage) laws applied to complex, multi-loop networks.

•  Electromagnetism & Measuring Devices

  • Magnetic Effects of Electric Current: Magnetic flux density in straight wires, circular coils, and solenoids.

  • DC Analog Measuring Instruments: Galvanometer theory, conversion to Ammeters (shunt resistance), and Voltmeters (multiplier resistance).

•  Electromagnetic Induction & AC Machinery

  • Electric & Magnetic Induction: Faraday’s law, Lenz’s rule, self-induction, and mutual induction.

  • Alternating Current Machines: Electric generators (Dynamo), AC transformers (step-up/step-down), and DC motors.

• Introduction to Modern Physics

  • Dual Nature of Wave and Particle: Blackbody radiation, Planck’s quantum hypothesis, the Photoelectric effect, and Compton scattering.

  • Atomic Spectra & Modern Technology: X-rays, Laser principles and characteristics, and fundamental solid-state electronics.

What You Will Gain
