Answer :

Ac is alternating current, it means changing current, and dc is direct current. It means no changing, there for we only store the dc current. Battery is from two types of cell Anode and cathode, the direct current we connect to a battery with same polarity for store we can easily store dc. Dc current goes through the same cathode and to anode and save the charge.

Answer :

Current is made by potential difference between two electrodes with change of chemical energy to electrical with two charge point...

Ac have alternating positive and negative..chemical change does not reactive alternatively
by

Answer :

Because the direction of the current changes in AC electricity, you cannot directly store the power. Placing a capacitor in an AC circuit has no effect on the alternating flow of the electricity. The only way it can e stored is indirectly, by storing DC and then using a power inverter to convert the DC to AC.
