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:How to select power adapter

he same or similar voltage. The nominal input voltage on your computer is 16V, and the rated output voltage of the adapter is 20V, the difference is larger, so it can not be replaced

Q:Effect of inductor

If there is no current in the inductor, it prevents the current from flowing through it; if the current flows through it, it will attempt to maintain the current when the circuit is disconnected.

Q:How to choose the high quality inductor?

The so-called performance parameters generally refers to: inductance, rated current, quality factor and the size of the shape is in line with the requirements, etc.

Q:Laptop power adapter is used to do

the production of 1.8V, 3.3V, 5V and many other groups, such as CPU voltage for the memory component operation

Q:Using a multimeter to check whether the output voltage, and the rated output voltage line adapter nominal, can allow for 5% error

such as an adapter with 5V and 1A, then it is 5V * 1A = 5W, 5V = 5 and 5W 25 square in Europe, select 5 Euro 5 Watt dummy resistance test adapter performance, such as whether overheating after output voltage fluctuation phenomenon

Q:What is the difference between a power adapter and a voltage regulator?

generally consists of a shell, a power transformer and rectifier circuit, according to the type of output can be divided into AC output type and DC output type

Q:What is a power adapter, what is the use of

The power adapter (Power adapter) is the power supply equipment transform small portable electronic equipment and electronic appliances,

Q:Inductance is the sensor?

Inductance is an attribute of a closed loop formed by the winding of a wire

Q:How to classify inductors

Can also be divided into fixed inductors and adjustable inductors.
