Q:Inductance is what concept?: The coil core than the coil inductance without core coil core permeability volume; the greater the inductance is greater.

Q:What is inductance effect: The ratio of the change of the magnetic flux to the amount of the change of the current is called self inductance

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:How to select power adapter: if you look at symbol and laptops are not the same, it is absolutely impossible.

Q:Laptop power adapter is used to do: the production of 1.8V, 3.3V, 5V and many other groups, such as CPU voltage for the memory component operation

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

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:How to classify inductors: Can also be divided into fixed inductors and adjustable inductors.

Q:The function of computer monitor power adapter: 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:What are the main parameters of inductance?: Usually, the more coils, the more dense the winding, the greater the inductance.
