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: What is the role of inductance in the power supply: The effect of inductance is to prevent the change of electric current

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 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: What is a power adapter, what is the use of: The power adapter (Power adapter) is the power supply equipment transform small portable electronic equipment and electronic appliances,

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 inductance effect: Any current in the circuit produces a magnetic field, and the magnetic flux of the magnetic field acts on the circuit.

Q: Inductance works?: Inductance refers to the coil in the magnetic field activity, can be induced by the intensity of the current unit is "Henry" (H)

Q: How to select power adapter: the rated output current of the power adapter shall not be less than the rated input current of the computer.

Q: What are the main parameters of inductance?: Usually, the more coils, the more dense the winding, the greater the inductance.
