Q:The role of inductance in the circuit
DC: the so-called direct current refers to the DC circuit, the role of inductance is equivalent to a wire, can not play any role
Q:Why use inductance
transformer can exchange coupling, variable pressure and variable flow and impedance transformation etc..
Q:Is the inductor inductor
A reactor is also called an inductor. When a conductor is energized, a magnetic field is generated in a certain space occupied by it, so that all the current carrying conductors have a general sense.
Q:What are the main parameters of inductance?
A quantity of inductance, also known as a physical quantity, which produces self inductance.
Q:Inductance is the sensor?
The interaction between the current and the coil is called electrical impedance, inductance is, unit is Henry (H)"
Q:Power adapter can be used when the charger
There are several items on the label of the power adapter.
Q:What is the difference between the ballast and the adapter
its essence is the ballast power supply circuit
Q:How to select power adapter
if you look at symbol and laptops are not the same, it is absolutely impossible.
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 choose the high quality inductor?
So in the selection of inductors, we have to pay attention to it: first, the higher the value of Q.
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
