It is the ratio of Insulation Resistance value of 1st
minute and 10th minute for any Electrical equipment.
Equipment is said to be sound if the ratio is greater than
one.

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 ?
