it is root mean square value.(ie)take one resister give
the supply(A.C) it will produce the some heat and give the
D.C supply to the same resistance the heat will
produce.while give the D.C supply it would producethe same
heat as in A.c supply that time the D.C cuurent value shows
the r.m.s. vlue of A.c current.
