Q:What is the difference between the ballast and the adapter
Generally refers to the power adapter suitable search orchestration,
Q:How to test the power adapter
such as an adapter with 5V and 1A, then it is 5V * 1A = 5W, 5V = 5 and 5W 25 square in Europe, select 5 Euro 5 Watt dummy resistance test adapter performance, such as whether overheating after output voltage fluctuation phenomenon
Q:Laptop power adapter is used to do
Laptop power adapter is the power supply department to provide 220V AC into low-voltage DC device for notebook computer power supply
Q:What is the difference between a power adapter and a voltage regulator?
Straightforward can be understood as a voltage converter, such as the 110-220 AC voltage into a fixed DC voltage
Q:What are the two functions of the inductor in the circuit
The inductor current change process does not hinder the consumption of electric energy
Q:Why inductors do not consume electricity
When the inductor is connected with the direct current, the inductance is charged, and the charge which is filled with the inductance two will never disappear
Q:What is the inductor
The inductor is similar in structure to the transformer but has only one winding
Q:How to select power adapter
The polarity of your notebook symbol is in the negative, the adapter of my pictures is not clear what is marked polarity
Q:How to determine whether the computer adapter is available
Today, there is a typhoon, the home of electricity is not stable, there will be no electricity for a while, and then I charge the laptop in the process, the computer did not boot
Q:How to classify inductors
Can also be divided into fixed inductors and adjustable inductors.
