when neutral will carry the current?what could be the
magnitude?

Answer Posted / satish panchal

Nuetral will carry current in unbalance & faulty / EF or SC
condition. During normal condition vector sum is Zero and
megnitude is also zero, but in faulty condition zero
sequence current will flow through neutral and megnitude
depends upon fault strenght.

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 ?
