Electric Current and Circuits
Learning Time: 5-15 hours
Content: Electric current and circuits is a subject that examines the movement of electric charges and the operation of circuit elements. This subject covers the definition of current (Ohm’s Law), resistance, series-parallel circuits, power consumption, and circuit analysis. The TYT focuses on basic circuit elements, while the AYT focuses on complex circuits and efficiency analysis. The current 2025 curriculum also covers renewable energy circuits and smart grids. Learning this topic forms the basis for electrical system design.
