Q:What is the role of inductance in the power supply

The effect of inductance is to prevent the change of electric current

Q:Linear adapter and switching power adapter

But the linear power supply EMI is low, but the switching power supply EMI is higher, especially the small power.

Q:Effect of inductor

The inductor is similar in structure to the transformer but has only one winding.

Q:How to choose the high quality inductor?

So in the selection of inductors, we have to pay attention to it: first, the higher the value of Q.

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:Using a multimeter to check whether the output voltage, and the rated output voltage line adapter nominal, can allow for 5% error

if possible, can be appropriate resistance as a false load, it can be generally choose to fake the load resistance

Q:Main parameters of inductor

The inductance of the main parameters, the allowable deviation, quality factor, distributed capacitance and rated current, etc..

Q:What is the difference between a power adapter and a voltage regulator?

The power adapter (Power adapter) is the power supply equipment transform small portable electronic equipment and electronic appliances

Q:What is the difference between transformers and inductors

high frequency magnetic circuit can be open, such as iron oxygen and air core coil, low frequency magnetic circuit is closed, such as iron core and ferrite core

Q:Is Australia's power adapter the same as Europe?

Australia is all like China tripod socket, plug pin 2 is inserted below the feet of the tripod and Chinese as plug
