Q: What is the difference between the power adapter and the power converter?: The power converter is mainly used to convert a form of socket into a different form or socket, as well as mobile phone charging, electric vehicles are also a class of power converters

Q: Laptop power adapter are AC-DC dual-use: General notebook power adapter are DC output, AC DC converter.

Q: What is the role of inductance in the power supply: The effect of inductance is to prevent the change of electric current

Q: Main parameters of inductor: Inductance inductance of the size, mainly depends on the number of coils (turns), winding method, with or without the core and core materials, etc.

Q: Inductance has no direction?: The inductor is similar in structure to the transformer but has only one winding

Q: What are the two functions of the inductor in the circuit: The role is to impede the flow resistance current power consumption for the logo, change of inductance to impede current is purely to increase the current change

Q: What is the substitution principle of inductance?: An inductor (Inductor) is a device capable of converting electrical energy into magnetic energy.

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: Inductance works?: When the current in the coil is changed, the magnetic fields around also produced corresponding changes, this change can make the magnetic field coil induced electromotive force (EMF is used to represent the terminal voltage of the active element of ideal power source, this is the self).

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
