subject: Detailed Tips For Beginners - Equip Yourself With 12v Transformer [print this page] Nowadays, most of the things that you use are related to electronics. And more and more people will study subjects like electronics in the universities. Factories or companies are making new electrical applications day by day.
They way that transformer works is something simple actually. One hand of the transformer is connected to the main power supply, which will provide electricity of about hundreds of volts. Then, there will be some coils winding in the transformer. On the other side of the transformer, there will be a small number of turns of windings and then the applications that you want to supply electricity on will be there.
In this way, the voltage supplied to the application will be only of about dozens of volts. This is the work of the step-down transformer. The winding turn ratio is proportional to the voltage ratio between the circuits. Of course, there will be step-up transformers, such as the electricity power cable transmission, but this is not something that we would pay attention to in normal life.
12V is commonly used to run the electrical applications nowadays. For example, the lights will be operated using this voltage. And this increases the popularity of the 12V lighting transformer. This is one type of transformers which can allow people to switch on the lights like the neon lamps. If the voltage supplied is too high, the lamps or the lights will burn and this is something bad to people, especially business owners because they have to spend money to replace those lights.
If you charge your mobile phone without a 12V transformer, your mobile phone will surely explode because the battery cannot tolerate a high charging voltage. This is something about physics and if you think that it is too complicated, just bear one simple thing in mind.You should never try to charge the dedicated electrical applications without using a 12V transformer.
12V one is the most common one and you will find that most of the chargers, including those for cell phones and camera, will need to be charged under this voltage.
If you wish to get the correct transformer for your application, you should try to look at the power rating, which is stated clearly on the machine and also on your transformer. 12V transformer is common and somehow universal to many electrical applications. The power from the transformer can be slightly higher than the number needed by the applications.
But when you are trying to look for a dc transformer, you may actually feel disappointed. Although you may claim that you had one in hand before, you should know that this type of tool cannot be a dc one actually. It can become a dc one just because some rectifiers are added to smooth the ac source and make it suitable to charge in dc mode. Of course, most of the transformers are now equipped with this application and you can choose freely.
