Introduction to Transformers (Full Lecture)

ERROR at 38:40 Sin = EpIp* In this lesson we'll examine the transformer, an electrical device used to step up or step down AC voltage. We'll learn the turns ratio, the number of turns on the primary over the number of turns on the secondary, is directly proportional to voltage and inversely proportional to current. Additionally, we'll learn that a source supplying current to an ideal transformer sees a reflected impedance equal to the load impedance times the turns ratio squared. We'll assume ideal transformers are 100% efficient, and operating under this somewhat dubious assumption, we can say power in equals power out. Finally, we'll learn that transformers are essential component of the modern electrical grid and make it possible to transmit electrical power over vast distances with minimal losses.
