We store the d.c supply...then why can't we store A.c supply???
Answers were Sorted based on User's Feedback
Answer / naresh_alf
the reason is when A.c supply is given the atoms get
thermally vibrated and dissipating energy in the form of
heat so ther is no chance of energy storage....
while coming to d.c supply the thermally vibrations are
absent....... that is the reason we can store the D.c but
not A.c.....

Answer / kamal kishore
We cannot store AC in batteries because AC changes their polarity up to 50 (When frequency = 50 Hz) or 60 (When frequency = 60 Hz) times in a second. Therefore the battery terminals keep changing Positive (+ve) becomes Negative (-Ve) and vice versa, but the battery cannot change their terminals with the same speed so that’s why we can’t store AC in Batteries.

Answer / bharat singh
we cannot store ac becouse it has two half + and - so when
we store + half it will stored but when in - half it will
discharge the stored + half
