DUE TO VARIATIONS IN VOLTAGES,VARYING MAGNETIC FIELD IS
PRODUCED & THIS VARYING MAGNETIC FIELD CHANGES DIMENSION OF
FERROMAGNETIC ELEMENT USED AS A TRANSFORMER ELEMENT & IT
APPEARS AS A VIBRASIONS.THIS VIBRATIONS ARE SOURCE OF THE
NOISE.

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 ?
