Introduction to Transformers (Full Lecture)

[Music] you [Music]

good day and welcome to Big Bad Tech I'm your instructor Jim Pytel and today's topic of discussion is transformers our objective is to examine the transformer an electrical device used to step up or step down AC voltage we'll examine how the turns ratio between the primary and secondary windings of an ideal transformer affect voltage and current

reflected impedance and power transfer the selector operates under the presumption in the viewer is more than a passing familiarity with AC power calculation as illustrated in the AC power an AC power examples lectures both available at the Big Bad TAC Channel if you haven't watch these lectures yet or only dimly recall their contents please

take the time to do so now let it be known upfront this lecture is not about the comic book the television series nor the truly awful movie franchise based on the popular transformer series of toys from the dark ages of culture the 1980s but rather one of the most useful electrical devices ever invented also

over the same name without overstating their importance transformers are absolutely essential to modern society make it possible to not only transmit electrical power over vast distances but also power a range of industrial devices using standardized distribution voltages transformers have had a profound impact on the way our society makes use of electrical power any individual

knowledgeable about the function and construction of transformers can assure you that there is indeed more than meets the eye a transformer as a device composed of no moving parts used to step up or step down or if you want to think of it this way transform voltage a transformer does so through the process of
