sir A.C has no polarity okay but i mean that when we interchange multimeter terminal in the dry battery terminals then the reading is zero i have also tested the same with other meter also
sir in a wet battery when we measure ripple voltVac is higher than actual D.C voltage it is noted in dry battery alsoie 1.5 v battery measure 2.1 v in A.C further if we inerchange polarity in the multi meter A.C volt is zero reason may be expalained
sir itis noted while checking 4 a ripple content across a wet bat using digital multimeter ripple voltage (Vac) was found 2 be higher than bat voltage reason may be explained . when the polarity is inter changed in the multi the reading is zero
