transformador eléctrico 27
I was going to send this consultation to see transformer and electrical, because I do not remember another transformer that is not electric; but it turns out that it is the name of those who pass power for power, and so they differ p. E.g. of the 'impedance transformer', which is still electric but for another use. This is a static machine that connects to alternating electricity and delivers the same power it takes, but you can do it with different voltage and current.
