Q:What are the two functions of the inductor in the circuit

The inductor current change process does not hinder the consumption of electric energy

Q:What is the difference between the power adapter and the power converter?

The utility model is mainly used for supplying power to another electric appliance

Q:Why inductors do not consume electricity

When the inductor is connected with the direct current, the inductance is charged, and the charge which is filled with the inductance two will never disappear

Q:What is the substitution principle of inductance?

Inductor has a certain inductance, it only hinder the current changes

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 a mobile power supply and a power adapter?

The mobile power supply is the voltage and current that has been stored in the power supply to the mobile phone.

Q:Inductance works?

When the current in the coil is changed, the magnetic fields around also produced corresponding changes, this change can make the magnetic field coil induced electromotive force (EMF is used to represent the terminal voltage of the active element of ideal power source, this is the self).

Q:Power adapter can be used when the charger

There are several items on the label of the power adapter.

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 the difference between the ballast and the adapter

its essence is the ballast power supply circuit
