What are Step-up and Step-down Transformers? This is a very useful device, indeed. With it, we can easily multiply or divide voltage and current in AC circuits. Indeed, the transformer has made the long-distance transmission of electric power a practical reality, as AC voltage can be “s...
A transformer is a static electrical device, used to transfer the energy in electrical form between two or number of circuits. The main function of a transformer is to change the alternating current from one voltage to another voltage. The transformer doesn’t have any moving parts and works o...
Transformers Transformer is a passive electrical device that converts voltage and current through electromagnetic induction. There are two types of transformer: the step-up transformer and step-down transformer. The underlying physics that govern the operation of transformers is the Faraday's Law ...
