Q:What is the difference between a mobile power supply and a power adapter?
Mobile power supply capacity is generally 4000-12000mAh, is a portable external battery.
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:Linear adapter and switching power adapter
Linear power supply efficiency is low, but switching power supply efficiency is high.
Q:Inductance and capacitance how to understand?
It is a circuit parameter which describes the induced electromotive force in the coil or in the other coil due to the change of the coil current.
Q:What are the two functions of the inductor in the circuit
The inductor current change process does not hinder the consumption of electric energy
Q:What is the power adapter
, this is because in real life, electronic devices are often not directly use household power
Q:The role of inductance in the circuit
Any of the current in the circuit, will produce a magnetic field, the magnetic flux and the circuit.
Q:Inductance is the sensor?
The interaction between the current and the coil is called electrical impedance, inductance is, unit is Henry (H)"
Q:How to classify inductors
The adjustable inductor is divided into a magnetic core adjustable inductor, a copper core adjustable inductor, a sliding contact adjustable inductor, a series mutual inductance adjustable inductor and a multi tap adjustable inductor.
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
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
