Q: What is the role of inductance in the power supply: Basic function: argument filtering, oscillation, delay, wave trapping image: "through DC, AC DC resistance" refers to: the so-called DC in DC circuits, inductance effect is equivalent to a wire, does not play any role

Q: Main parameters of inductor: The inductance of the main parameters, the allowable deviation, quality factor, distributed capacitance and rated current, etc..

Q: The role of inductance in the circuit: DC: the so-called direct current refers to the DC circuit, the role of inductance is equivalent to a wire, can not play any role

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: 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: 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 difference between a mobile power supply and a power adapter?: Mobile power supply capacity is generally 4000-12000mAh, is a portable external battery.

Q: Inductance works?: Also refers to the use of this property made of components. Inductor and transformer (inductor) are insulated conductor (e.g. enameled wire, wire etc.) electromagnetic induction element formed by winding

Q: What is the difference between the ballast and the adapter: Generally refers to the power adapter suitable search orchestration,

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