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:Why use inductance

it can be composed of resistors or capacitors of high or low pass filter, phase shifter circuit and resonant circuit

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:Main parameters of inductor

Inductance, also known as self inductance, is a physical quantity that represents the inductance of the inductor.

Q:What is the inductor

The inductor is similar in structure to the transformer but has only one winding

Q:How to determine whether the computer adapter is available

Today, there is a typhoon, the home of electricity is not stable, there will be no electricity for a while, and then I charge the laptop in the process, the computer did not boot

Q:What is the difference between the ballast and the adapter

Generally refers to the power adapter suitable search orchestration,

Q:Is Australia's power adapter the same as Europe?

Australia is all like China tripod socket, plug pin 2 is inserted below the feet of the tripod and Chinese as plug

Q:Laptop power adapter are AC-DC dual-use

The power adapter (Power adapter) is the power supply equipment transform small portable electronic equipment and electronic appliances, generally consists of a shell

Q:What is inductance effect

An inductive device is called an inductor (inductor, which is generally referred to as an inductor in Chinese), and the inductor is usually a coil, which can gather the magnetic field.
