regulation of transformer is the %decrease in voltage when
load is applied on it..whereas in case of alternator when
load is applied its output voltage decreases in comparison
to that when it was operating at no load...and in case of
transmission line it is same...
regulation is change in output when load is applied so it
is same for all
