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:What is the power adapter
The power adapter (also called the external power switch power adapter)
Q:Why inductors do not consume electricity
but because of the charge discharge inductance does not stop in the AC circuit in the theory that the power inductor made useless, useless power consumption of inductance.
Q:What is the inductance component
The inductor is composed of skeleton, winding, shield, packaging material, core or core.
Q:The role of inductance in the circuit
On the basis of Lenz's law, the magnetic flux will borrow the voltage by induction (EMF) and tend to resist a change in current. The ratio of change in magnetic flux changing the amount of current is called self inductance,
Q:What is the inductance
skeleton skeleton refers to the winding coil bracket. Some of the fixed volume inductor larger or adjustable inductor (such as oscillation coil, choke etc.)
Q:Is Australia's power adapter the same as Europe?
Japan is 100V, most of Europe is also 220V, but for example France is 127V and 220V dual voltage.
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: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:How to classify inductors
The adjustable inductor is divided into a magnetic core adjustable inductor, a copper core adjustable inductor, a sliding contact adjustable inductor, a series mutual inductance adjustable inductor and a multi tap adjustable inductor.
