Is a DC Transformer Possible? if Yes, Then Why, if not Then Why?
Answer Posted / naresh
it is possible for small applications.the ransformer will
work for small period of time for given DC input as it will
produce little amount of flux for some time, but not
constant.as the flux is not constant, we prefer AC
transformer.
