Why Can''t We Store AC in Batteries instead of DC?
Why we can''t store AC in Batteries instead of DC.or Can we store AC in batteries instead of DC? We cannot store AC in batteries because AC changes their polarity upto 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 …

Solution. We start by making a circuit diagram, as in Figure (PageIndex{7}), showing the resistors, the current, (I), the battery and the battery arrow.Note that since this is a closed circuit with only one path, the current through the battery, (I), is the same as the current through the two resistors. Figure (PageIndex{7}): Two resistors connected in series with a …
Why Do Batteries Get Heated?
So this heat created by the product of current passing through this internal resistance of the battery can increase the temperature of a battery system. This is the reason in a battery management system, we must have a thermal management system in order to make sure the battery system remains cool and does not overheat.
Why AC current lose less power over long distances than DC?
The AC eventualy won and the main reason was that transformer does not work with DC. This means that in AC systems you could easily transform electricity to higher voltage (10 kV or more) and lower current for transmission, and then transform back to lower voltage (110 V or 220 V) for distribution.

Why is the charge transferred by electrons and not by protons?
You can totally transfer charge using protons. Or using Na+ or any kind of charged particle. It happens all the time - if you look at how a wet cell battery works, you''ll find that while charge across the wire is carried by electrons, current flows along the salt bridge via charged ions (theoretically protons could be among these). I bet if you could somehow make a superfluid …

The War of the Currents: AC vs. DC Power
Edison developed direct current -- current that runs continually in a single direction, like in a battery or a fuel cell. During the early years of electricity, direct current (shorthanded as DC) was the standard in the U.S. But there was one problem. Direct current is not easily converted to higher or lower voltages.
