Q:What is inductance effect
The ratio of the change of the magnetic flux to the amount of the change of the current is called self inductance
Q:What is the difference between the ballast and the adapter
but the ballast is the special power supply of fluorescent lamp (electrical characteristics of fluorescent lamp special)
Q:Linear adapter and switching power adapter
Linear power supply refers to the adjustment of the power supply pipe in a linear state, while the switching power supply regulator works in the switch state
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:Is the inductor inductor
However, charged straight conductor inductance is small, the magnetic field generated by the strong, so the actual reactor is conducting wire into a solenoid, said hollow reactor; sometimes in order to make the solenoid has larger inductance, then inserted into the core in the solenoid, said iron core reactor.
Q:Inductance and capacitance how to understand?
The interaction between the current and the coil is called electrical impedance, inductance is, unit is Henry (H), named after the American scientist Joseph Henry.
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:Main parameters of inductor
The inductance of the main parameters, the allowable deviation, quality factor, distributed capacitance and rated current, etc..
Q:Why use inductance
The basic function of inductive argument: effect of filtering, oscillation, delay, wave trapping image:
Q:Effect of inductor
Inductor has a certain inductance, it only prevents the current changes
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
