Electrical energy storage is not possible.But chemical
energy storage is possible. so,we are covert electrical in
to chemical energy.
Chemical energy having positive ions and negative ions
only. same time DC sopply also having positive and negative.
(DC supply Only use in charging process/Chemical process)
AC supply having cycles (sine wave)positive half
cycle,negative half cycle. Its not Sutible for Chemical
process.
So we are use only DC Supply

why we use single core 630mm2 cable for transformer secondary side
