Batteries

Assalamu’alaikum every body. Good morning sir, good morning friends. In this opportunity, I want to tell you all, everything about part of electronics, that always we used everyday as a source voltage. It is a battery.

Before learn more about a battery, let‘s review the history first. Battery was found by Alesandro Volta in 1800. So, it is also called volta cell. Alessandro Volta is an Italian physicist Then Benjamin Franklin gave it a name “battery”. And it is popular until now. In 1834, Michel Faraday was perfecting this cell. And now, it is grow up and be one of most source voltage that very important in many electronics devices. For your hand phone, your notebook, watch, calculator, etc.

Battery is a devices that converts chemical energy directly to electrical energy. It is consist of one or more voltaic cells. Each voltaic cell consist of two half cells connected in series by a conductive electrolyte containing anions and cations. There are many parts of the battery. There are metal cover, plastic cover, a carbon, and ferrite stalk. And it is have two poles. An anode and cathode. An anode is a positive poles of battery. It is a ferrite stalk. And a cathode is the reverse side of anode. It is a negative pole of battery. The part of battery that be a negative pole is a carbon.

As we all already understood that battery is divided into two kinds. A rechargeable battery and un rechargeable battery. In physic, both of them are same. It is almost have no different. But the different is on materials. So you must be care full in using it. Read the using instruction. Because, if you recharge un rechargeable battery, the battery may can explode. So, it is dangerous if you not use it as should have been use.

Battery is one of many kinds source voltage. It is directing current source voltage. Every time, every where, we always use it. There are many kinds and types of batteries. For example, microphone batteries .Like this batteries. The shape is rectangular. It is a battery that usually used to supply voltage in wireless microphone. It is very light in weight, but have a voltage until nine volts. So, it is very portable. And beside that, it is no mercury added, so it is kind for humanity .

The other example, is one a half volts battery. The shape is like a can. There are many sizes, due to the necessity. It is also divided into two kinds. Rechargeable and un rechargeable. It is a kind of batteries that we often found. Next example, lithium battery. Generally, it is type a rechargeable battery. Usually, it is used in hand phone. The shape is thin, slight. Like this battery. It is usually reach three point seven volts DC.

Okay every body, that is a kinds and types of batteries. So if you want to use the battery to your electronics devices, you must understand what type of battery that you choose. So it is will work perfectly. And you also must be care full in recharge the batteries. Because, not all battery can be recharge. If you recharge an un rechargeable battery, maybe it can explode and dangerous.

Okay everybody, that way a full of my presentation about battery. I hope in every our presentation, always give us more knowledge. Finally, thank you for your attention. My name is Sholl and Wassalamu’alaikum.
