Q:What is inductance effect
According to Lenz's law, the flux tends to resist the change of electric current by the induced voltage (back EMF).
Q:Why use inductance
The basic function of inductive argument: effect of filtering, oscillation, delay, wave trapping image:
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:Inductance is what concept?
The coil core than the coil inductance without core coil core permeability volume; the greater the inductance is greater.
Q:Effect of inductor
Inductor has a certain inductance, it only prevents the current changes
Q:What is the difference between a power adapter and a voltage regulator?
Straightforward can be understood as a voltage converter, such as the 110-220 AC voltage into a fixed DC voltage
Q:Linear adapter and switching power adapter
Linear adapter and switching power adapter is also known as linear power supply and switching power supply
Q:Main parameters of inductor
Usually, the more coils, the more dense the winding, the greater the inductance
Q:What is the role of inductance in the power supply
Basic function: argument filtering, oscillation, delay, wave trapping image: "through DC, AC DC resistance" refers to: the so-called DC in DC circuits, inductance effect is equivalent to a wire, does not play any role
Q:How to choose the high quality inductor?
When using inductor, there is no doubt that the performance parameters
