Q: What is the difference between the power adapter and the power converter?: The power adapter is an interface converter, which can be an independent hardware interface device that allows hardware or electronic interfaces to be connected to other hardware or electronic interfaces, as well as information interfaces.

Q: Main parameters of inductor: Inductance, also known as self inductance, is a physical quantity that represents the inductance of the inductor.

Q: The role of inductance in the circuit: On the basis of Lenz's law, the magnetic flux will borrow the voltage by induction (EMF) and tend to resist a change in current. The ratio of change in magnetic flux changing the amount of current is called self inductance,

Q: What is the difference between transformers and inductors: high frequency magnetic circuit can be open, such as iron oxygen and air core coil, low frequency magnetic circuit is closed, such as iron core and ferrite core

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: 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: Using a multimeter to check whether the output voltage, and the rated output voltage line adapter nominal, can allow for 5% error: if possible, can be appropriate resistance as a false load, it can be generally choose to fake the load resistance

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: What is the inductance: skeleton skeleton refers to the winding coil bracket. Some of the fixed volume inductor larger or adjustable inductor (such as oscillation coil, choke etc.)

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