Dc transformer does not exists. because the tranformer
function is to tranfer the power from one circuit to another
circuit. but in dc the flux induced is not flctuating its
constant. so this flux will not induce the flux in secondary
(cutting of flux linkage not happening)

I don't understand why when we connect high voltage source in DC to electronic motor , we must add capacitor and resistor in parallel ? (I know that we use capacitor because we want to absorb the current that in the first second electronic motor in opposed with current course produce. ) what are the feature of Resistor and in such situation ?
