Answer / moorthi k

AC voltage have positive and negative voltage alternatively
sign wave form shape so positive and negative voltage are
equal to zero so cannot be stored

Answer / rahul bisht

ac is a most higher current comperision by DC because DC is a constant current and ac is induction and fluxuation current and not a constant current and ac frequency 50hz and DC 0..than ac is not stor...may be.........

Answer / ann

ac cannot be stored because it produced in bulk amount it is hard to stored ac ....

We have two Al.busbars each of size 125mm*10 mm connected in parallel.To increase the current rating ,can we connect third busbar of size 100mm*10mm in parallel to existing two busbars?In my opinion ,if we connect busbars of different sizes in parallel,then the busbar of lowest size will take much current.So this type of paralleling should be avoided .Am I correct?
