Q: The function of computer monitor power adapter: The first is the model, it tells us manufacturers, Watts and other information;

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: Why inductors do not consume electricity: but because of the charge discharge inductance does not stop in the AC circuit in the theory that the power inductor made useless, useless power consumption of inductance.

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: Inductance is what concept?: The inductance of the inductor, the allowable deviation, the quality factor, the distributed capacitance and the rated current.

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: How to choose the high quality inductor?: When using inductor, there is no doubt that the performance parameters

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 are the main parameters of inductance?: Usually, the more coils, the more dense the winding, the greater the inductance.

Q: The value of the inductance is determined by what: The method of reducing the Q value can be to increase the resistance of the winding or to use the magnetic core with large power consumption
