Electrical Force, Potential, and Work
Learning Time: 5-15 hours
Content: Electrical force, potential, and work are subjects that examine the interactions and energy transformations between electric charges. This subject covers Coulomb’s Law, electric potential energy (U = k.q₁.q₂/r), potential difference (V = W/q), and electrical work calculations. TYT focuses on fundamental forces and potential, while AYT focuses on complex systems and applications. The current 2025 curriculum also covers renewable energy storage and electric vehicles. Learning this topic forms the basis for the analysis of electrical systems.
