# Which current is in battery, AC or DC?

Have you ever wondered the difference between AC power and DC power, or have you asked yourself which current battery use AC or DC? Well, if you have, then read on because I am about to tell you.

## Which current is in battery, AC or DC?

AC stands for Alternating Current. This is what your home outlets are using – it’s a type of electricity that changes directions at regular intervals.

DC stands for Direct Current. This is what batteries use. This kind of electricity flows in the same direction all the time (it doesn’t alternate).

They both sound like they do similar things, but there are some key differences between them. To explain this further, let’s site an example.

Imagine you’re at the front of a rowboat pulling on one oar. If your friend is pushing against the back of the boat, then moving it forward, that person is producing Direct Current (DC). Alternating Current (AC) would be if every few seconds, they stopped pushing and started pulling in order to move the boat forward.

## How does DC power work in a battery?

DC power or direct current is the unidirectional flow of electric charge. This means that it only flows in one direction and never changes its polarity. The electricity starts at a negative voltage terminal called the anode and ends at positive voltages terminal known as a cathode. There are plenty of different kinds of batteries, but they all share this similarity.

In addition, AC power or alternating current that you can find in your homes that are wired can convert power from AC to DC power. The most frequent approach to transform alternating current into the direct current is to use one or more diodes, which are tiny electronic components that allow current to flow in one direction but not the other. A rectifier, filter, or transformer may also be used to convert alternating current (AC) electricity into direct current (DC).

DC electricity has a wide range of applications and purposes. We use a lot of electrical equipment that needs DC-powered batteries to be connected or linked to our electricity sources using AC adapters like smartphones, flashlights, TVs, and more.

## Does a car battery use DC power?

A car battery uses DC power. It is automatically wound by an alternator, which is almost always a three-phase AC generator. Of course, the output of the alternator windings is immediately converted to DC within the alternator.

## Can you store Alternating Current power to batteries?

Unfortunately, no. There are reasons for this like a battery does not directly contain electrical energy. The battery converts electrical energy into chemical energy.

You can’t store Alternating Current power to batteries because AC changes its polarity up to 50 (When frequency = 50 Hz) or 60 times per second. As a result, the battery’s terminals cannot be changed with the same frequency, thus we can’t store AC in batteries.

## Is DC power stored in batteries?

Batteries do not store direct DC power. Batteries convert direct current to chemical energy. The chemical energy is used as the DC store. When the battery is connected to a load, chemical energy is reconverted back into direct current.

## Is it feasible to charge a DC battery through AC power?

Many people think that it isn’t possible and this can cause problems in the future. The answer to this question is no, not in a direct way. By utilizing a rectifier, you may charge a DC battery with AC. The AC will then be rectified, and the DC electricity is supplied to the DC battery.

## Can you consider that battery is a source of energy?

It is awesome to know that battery can store energy. But, no one would say batteries are a source of it. It turns out they just provide an easy way for you to get your hands on power when needed. Batteries are pretty simple devices – store up some juice from electrical currents, then release this stored power when called upon by another circuit or individual device requiring assistance.

In general, we store things in preparation for their future usage. Energy is stored as a backup in case of an emergency. As a result, batteries simply act as energy reservoirs.

In conclusion, it can be overwhelming and confusing to know about AC and DC currents. But understanding how these currents work and what they can do for in a specific device or gadget will help you know more about them. This way, you’ll be equipped with the proper knowledge to choose which one is right for you and your device. I hope that the information that I’ve shared with you will assist you in which current should work for your batteries.
