Alternating Current and Transformers
Learning Time: 5-15 hours
Content: Alternating current and transformers is a subject that examines the transmission and voltage transformation of time-varying current. This subject covers the definition of alternating current, RMS value, phase difference, operating principles of transformers (ideal and real), efficiency, and practical applications. TYT focuses on basic AC circuits, while AYT focuses on transformer design and losses. The current 2025 curriculum also covers smart grids and electric vehicle charging systems. Learning this topic forms the basis for electricity distribution.
