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

AC resistance: in the AC circuit, the inductance will have an impedance, that is, XL, the current of the circuit will become smaller, a certain degree of obstruction to the exchange.

Q:The value of the inductance is determined by what

It was also reduced the Q value of the inductor, the purpose is to avoid high frequency resonance / gain is too large

Q:Laptop power adapter is used to do

the production of 1.8V, 3.3V, 5V and many other groups, such as CPU voltage for the memory component operation

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

Adapters are constantly transformed and cannot be fully charged

Q:Is the inductor inductor

A reactor is also called an inductor. When a conductor is energized, a magnetic field is generated in a certain space occupied by it, so that all the current carrying conductors have a general sense.

Q:What is the difference between the ballast and the adapter

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:What is the power adapter

, this is because in real life, electronic devices are often not directly use household power

Q:What is inductance effect

The ratio of the change of the magnetic flux to the amount of the change of the current is called self inductance
