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 ?
For an 100kw generator, only 50kw of load is connected. will the generator generate only 50kw or 100kw. if it generate 100kw what happens to rest of the 50kw. what happens if we connect more than 100kw of load?
