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.
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:Inductance has no direction?
The inductor is similar in structure to the transformer but has only one winding
Q:Effect of inductor
An inductor is a device that converts electrical energy into magnetic energy
Q:What is the inductance
The skeleton is usually made of plastic, bakelite, ceramics, can be made into different shapes according to actual needs
Q:What is the difference between the power adapter and the power converter?
For example: power adapter, tripod base adapter components, USB and serial switching equipment, etc..
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.
Q:What is the role of inductance in the power supply
AC resistance: in the AC circuit, the inductance will have an impedance, that is, XL, the current of the circuit will become smaller, a certain degree of obstruction to the exchange.
Q:How to test the power adapter
if possible, can be appropriate resistance as a false load, it can be generally choose to fake the load resistance
Q:How to determine whether the computer adapter is available
but also connected with the power adapter, a few minutes later heard a voice adapter immediately, pull the power, and then found the smell like
