In the office again.

Is this not 60% of 12kw ie 7.2 kwie 12/100 * 60

or 12 * 0.6
To try and help:

60% is 6 tenths.

if 12KW motor, divide by ten

=1.2KW

then times 6 (six tenths)

=7.2KW (as posted by Mr Apache)

These "efficency" problems are really maths - standard percentages.

Forget the electrical connotations; just deal with the numbers m8.

Again, well done Apache.Applaud Smiley
