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

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

Q: The role of inductance in the circuit: Any of the current in the circuit, will produce a magnetic field, the magnetic flux and the circuit.

Q: What is the difference between transformers and inductors: A wide range of inductors and Transformers: working frequency is the frequency (50Hz), can also be a radio waves (such as more than a few hundred MHz

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: 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 mobile power supply and a power adapter?: The mobile power supply is the voltage and current that has been stored in the power supply to the mobile phone.

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: Laptop power adapter is used to do: Laptop power adapter is the power supply department to provide 220V AC into low-voltage DC device for notebook computer power supply

Q: The value of the inductance is determined by what: It was also reduced the Q value of the inductor, the purpose is to avoid high frequency resonance / gain is too large
