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
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
l, a power transformer and rectifier circuit, the working power supply of AC (alternating current standard in China for the exchange of 220V),
Q:Why use inductance
through DC, AC resistance" refined commentary: in electronic circuits, inductance coil of AC current limiting effect
Q:Inductance is the sensor?
When the coil passes through the current, a magnetic field is formed in the coil, and the induced magnetic field generates an induced current to resist the current flowing through the coil.
Q:The function of computer monitor power adapter
Second is INPUT (input), in China is generally 100-240V~50-60Hz, which shows that it can work under the normal voltage 100V-240V
Q:Power adapter can be used when the charger
There are several items on the label of the power adapter.
Q:Inductance works?
it is also one of the components used in electronic circuits, related products such as film filter etc
Q:What is the power adapter
it is to supply a small portable electronic equipment and electronic variable sub device
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
We are a focus on the production of switching power supplies and power adapters and other power products for high-tech enterprises. Shenzhen power adapter, power adapter manufacturers, switching power adapter, switching power supply manufacturers, charger manufacturers, USB power adapter, 12V power adapter
