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

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

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:Why inductors do not consume electricity

When connected to AC inductance, different charging and discharging, does not consume power,

Q:What is the substitution principle of inductance?

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

Q:Main parameters of inductor

Usually, the more coils, the more dense the winding, the greater the inductance

Q:What is the difference between a mobile power supply and a power adapter?

Mobile power supply capacity is generally 4000-12000mAh, is a portable external battery.

Q:Power adapter can be used when the charger

Second is INPUT (input), in China is generally 100-240V~50-60Hz, which shows that it can work under the normal voltage 100V-240V

Q:How to classify inductors

According to the different structure of the inductor, the inductor can be divided into single layer and multi-layer inductors, FDC633W inductors with wound and inter winding, and a skeleton and no skeleton inductor

Q:Inductance and capacitance how to understand?

It is a circuit parameter which describes the induced electromotive force in the coil or in the other coil due to the change of the coil current.

Q:Laptop power adapter are AC-DC dual-use

l, a power transformer and rectifier circuit, the working power supply of AC (alternating current standard in China for the exchange of 220V),
