Q:The function of computer monitor power adapter

Third is OUTPUT (output), voltage * current = power, it can calculate the number of watts

Q:What are the two functions of the inductor in the circuit

it will hinder the current increase of electric energy in the magnetic field in the form of temporary storage

Q:Linear adapter and switching power adapter

But the linear power supply EMI is low, but the switching power supply EMI is higher, especially the small power.

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?

. Two inductance coil inductance at the same time, according to the definition of Q value (XL/R) selection of small scale values

Q:Why inductors do not consume electricity

When connected to AC inductance, different charging and discharging, does not consume power,

Q:How to classify inductors

Fixed inductors are divided into hollow inductors, inductance, iron core inductor, according to its structure and shape of pin mode can be divided into vertical to horizontal axial pin pin inductors

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:What is the power adapter

The power adapter (also called the external power switch power adapter)

Q:What is inductance effect

An inductive device is called an inductor (inductor, which is generally referred to as an inductor in Chinese), and the inductor is usually a coil, which can gather the magnetic field.
