Q: What is the difference between the power adapter and the power converter?: The utility model is mainly used for supplying power to another electric appliance

Q: Linear adapter and switching power adapter: Linear power supply refers to the adjustment of the power supply pipe in a linear state, while the switching power supply regulator works in the switch state

Q: What is the role of inductance in the power supply: Capacitance is simply a container for storing electric charge"

Q: Is the inductor inductor: However, charged straight conductor inductance is small, the magnetic field generated by the strong, so the actual reactor is conducting wire into a solenoid, said hollow reactor; sometimes in order to make the solenoid has larger inductance, then inserted into the core in the solenoid, said iron core reactor.

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: Inductance has no direction?: To discuss the situation: in the general filter circuit, the direction is not large; but if used in the PWM output inductance, this direction is too critical.

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: What is inductance effect: According to Lenz's law, the flux tends to resist the change of electric current by the induced voltage (back EMF).

Q: What is the inductor: . Inductor has a certain inductance, it only hinder the current changes.
