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:Why use inductance

it can be composed of resistors or capacitors of high or low pass filter, phase shifter circuit and resonant circuit

Q:What is the difference between an inductor and a sensor?

The inductor is similar in structure to the transformer but has only one winding

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?

Straightforward can be understood as a voltage converter, such as the 110-220 AC voltage into a fixed DC voltage

Q:Power adapter can be used when the charger

Second is INPUT (input), in China is generally 100-240V~50-60Hz, which shows that it can work under the normal voltage 100V-240V

Q:What is the inductance

The skeleton is usually made of plastic, bakelite, ceramics, can be made into different shapes according to actual needs

Q:What is the inductor

If the inductor is in the absence of an electric current, it will try to block the current flowing through it when the circuit is switched on; if the inductor is in the state of current passing, it will try to keep the current

Q:How to determine whether the computer adapter is available

Today, there is a typhoon, the home of electricity is not stable, there will be no electricity for a while, and then I charge the laptop in the process, the computer did not boot

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)
