Q:What is inductance effect
An inductive device is called an inductor (inductor, which is generally referred to as an inductor in Chinese), and the inductor is usually a coil, which can gather the magnetic field.
Q:How to choose the high quality inductor?
The so-called performance parameters generally refers to: inductance, rated current, quality factor and the size of the shape is in line with the requirements, etc.
Q:What is the power adapter
The power adapter (also called the external power switch power adapter)
Q:Why use inductance
through DC, AC resistance" refined commentary: in electronic circuits, inductance coil of AC current limiting effect
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: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 is the substitution principle of inductance?
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 constant when the circuit is disconnected.
Q:Inductance is what concept?
Usually, the more coils, the more dense the winding, the greater the inductance.
Q:What is the difference between the ballast and the adapter
its essence is the ballast power supply circuit
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
