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
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
I think your meter is reading incorrectly. It is possible your AC meter is also displaying the DC voltage of the battery. That would explain why it changes when you reverse its polarity.
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
