what is difference between phase voltage 415volt and 440volt
If it is a motor connection that is being tested, engineers like to see it above 5 meg. In reality above 2 meg is fine.
The ISO length unit to use would be the cementer.
The same unit as you use to measure any mass. The SI unit for mass is the kilogram.
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.
I would use the metric unit is inches
Standard International unit (SI unit)
the square unit of....!
Milliliters is the metric unit to use for the capacity of a thimble.
If not use the standard unit, you won't get correct answers when calculating.
The answer depends on whatever best suits the unit to the question.
Atomic mass unit
It's SI unit is meters
