but the ballast is the special power supply of fluorescent lamp (electrical characteristics of fluorescent lamp special)
Q:Laptop power adapter are AC-DC dual-use
The power adapter (Power adapter) is the power supply equipment transform small portable electronic equipment and electronic appliances, generally consists of a shell
Q:Inductor and inductor coil is not a concept
When an electric current passes through the coil, a magnetic field is created around the coil
Q:What is the inductance component
Effect: resistance to the flow of DC, high frequency low frequency
Q:Inductance is what concept?
The inductance of the inductor, the allowable deviation, the quality factor, the distributed capacitance and the rated current.
Q:How to determine whether the computer adapter is available
Always worried that will affect the computer, so full after I put the adapter pull from the computer
Q:What is the difference between the power adapter and the power converter?
