The transformer is made of silicon steel sheets. After the transformer is energized, magnetic flux will be generated. The magnetic flux will cause force action between the silicon steel sheets, resulting in a buzzing sound. This is normal.

the role of the adapter is an electronic product that converts alternating current into direct current.

Power adapters with large space are generally built-in. Generally, the size of the adapter is not small. Small-sized machines are external. In order to save space, it is also convenient to replace. It's dangerous inside.

Some problems to be paid attention to when using the power adapter

There are generally several items on the label of the power adapter (hereinafter referred to as adapter) that need attention.

The power adapter of most notebook computers can be suitable for 100～240V alternating current (50/60Hz). Basically, most notebook computers have an external power supply, and use a power cord to connect to the host, which can reduce the size and weight of the host. Only a few models have the power supply built in the host.

There is a nameplate on the power adapter, which indicates power, input and output voltage and current and other indicators. Pay special attention to the range of input voltage. This is the so-called "travel power adapter". If you go to a country where the mains voltage is only 110V When this feature is very useful, some parallel-imported laptops are only sold in the country of origin. They do not have this compatible voltage design, and even have a single input voltage of 110V. If they are plugged in under the 220V mains voltage in our country, they will burn out.

The function of the power adapter is to convert the high voltage at home into a stable low voltage that can work, so that they can work normally. Without it, it will bring a lot of inconvenience to our daily use.
