Q:What is inductance effect
According to Lenz's law, the flux tends to resist the change of electric current by the induced voltage (back EMF).
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 a power adapter and a voltage regulator?
Straightforward can be understood as a voltage converter, such as the 110-220 AC voltage into a fixed DC voltage
Q:What are the main parameters of inductance?
There are five important parameters of inductance: inductance, allowable deviation, quality factor, distributed capacitance and rated current
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 difference between the power adapter and the power converter?
For example: power adapter, tripod base adapter components, USB and serial switching equipment, etc..
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:What is the difference between the ballast and the adapter
Generally refers to the power adapter suitable search orchestration,
Q:What is the role of inductance in the power supply
Capacitance is simply a container for storing electric charge"
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).
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
