Depends on the rating of the source. For the same electrical load, a higher voltage will require lower current, but there's no specific current associated with 440V.
what is difference between phase voltage 415volt and 440volt

About 220 volts. They're just different voltage levels. 440 volt services can provide more power than 220 volt services typically.
33 kV (not 'kv'!) is the standard primary-distribution voltage used in the UK's electricity supply system. Low voltage (400/230 V -not 440 V) is normally provided by transformers supplied from the 11-kV system, not the 33-kV system.
To calculate the RMS (Root Mean Square) of a set of values, you first square each value, calculate the mean of the squared values, and then take the square root of that mean. For the given values (440V, 220V, 110V), you would first square each value (440^2, 220^2, 110^2), then find the mean of these squared values [(440^2 + 220^2 + 110^2) / 3], and finally take the square root of that mean.
