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:Effect of inductor

If there is no current in the inductor, it prevents the current from flowing through it; if the current flows through it, it will attempt to maintain the current when the circuit is disconnected.

Q:Inductance is what concept?

Inductance inductance of the size, mainly depends on the number of coils (turns), winding method, with or without the core and core materials, etc.

Q:Inductance has no direction?

To discuss the situation: in the general filter circuit, the direction is not large; but if used in the PWM output inductance, this direction is too critical.

Q:Why inductors do not consume electricity

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

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 mobile power supply and a power adapter?

The mobile power supply is the voltage and current that has been stored in the power supply to the mobile phone.

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

it is to supply a small portable electronic equipment and electronic variable sub device
