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 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:Laptop power adapter are AC-DC dual-use
General notebook power adapter are DC output, AC DC converter.
Q:What is the inductance component
Inductor also known as inductance coil, is the use of electromagnetic induction principle
Q:What is the difference between transformers and inductors
made of silicon steel sheet iron core when the frequency is low, with a ferrite core for high frequency, high frequency is air core coil
Q:Inductance is the sensor?
The interaction between the current and the coil is called electrical impedance, inductance is, unit is Henry (H)"
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:Main parameters of inductor
Inductance, also known as self inductance, is a physical quantity that represents the inductance of the inductor.
Q:Inductance and capacitance how to understand?
capacitance (Capacitance), also known as "capacitance" refers to the given potential difference between the amount of charge storage, denoted as C, the international unit is Fala (F)
Q:How to choose the high quality inductor?
. Two inductance coil inductance at the same time, according to the definition of Q value (XL/R) selection of small scale values
