Q:The value of the inductance is determined by what

The method of reducing the Q value can be to increase the resistance of the winding or to use the magnetic core with large power consumption

Q:What are the two functions of the inductor in the circuit

it will hinder the current increase of electric energy in the magnetic field in the form of temporary storage

Q:How to select power adapter

if you look at symbol and laptops are not the same, it is absolutely impossible.

Q:Why use inductance

it can be composed of resistors or capacitors of high or low pass filter, phase shifter circuit and resonant circuit

Q:What is the difference between an inductor and a sensor?

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

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:What is the substitution principle of inductance?

Inductor has a certain inductance, it only hinder the current changes

Q:What is the inductor

If the inductor is in the absence of an electric current, it will try to block the current flowing through it when the circuit is switched on; if the inductor is in the state of current passing, it will try to keep the current

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

Q:What is the inductance component

Concept: components that produce inductance are collectively referred to as inductors
