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 inductance component
Concept: components that produce inductance are collectively referred to as inductors
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 are the main parameters of inductance?
Usually, the more coils, the more dense the winding, the greater the inductance.
Q:Laptop power adapter is used to do
The power adapter output low voltage DC power into the computer, through the computer motherboard power supply circuit for further processing
Q:The function of computer monitor power adapter
Third is OUTPUT (output), voltage * current = power, it can calculate the number of watts
Q:Power adapter can be used when the charger
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: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 select power adapter
the rated output current of the power adapter shall not be less than the rated input current of the computer.
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
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
