Motors and Generators
... A huge advantage of generating electricity as AC is that it allows us to use transformers. These change the ‘format’ of the electricity supply, changing from high to low voltage, or the reverse, without losing much energy as heat in the process. We develop the ideas behind the transformer in four st ...
