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:Power adapter can be used when the charger
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:The value of the inductance is determined by what
The method of reducing the Q value can be to increase the resistance of the winding or to use the magnetic core with large power consumption
Q:Is the inductor inductor
However, charged straight conductor inductance is small, the magnetic field generated by the strong, so the actual reactor is conducting wire into a solenoid, said hollow reactor; sometimes in order to make the solenoid has larger inductance, then inserted into the core in the solenoid, said iron core reactor.
Q:What is the substitution principle of inductance?
The inductor is similar in structure to the transformer but has only one winding.
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:What is the difference between transformers and inductors
made of silicon steel sheet iron core when the frequency is low, with a ferrite core for high frequency, high frequency is air core coil
Q:The role of inductance in the circuit
inductor is usually a coil, the magnetic field can be gathered. (the exception is mutual inductance)
Q:What is the difference between the power adapter and the power converter?
For example: power adapter, tripod base adapter components, USB and serial switching equipment, etc..
Q:Inductor and inductor coil is not a concept
When an electric current passes through the coil, a magnetic field is created around the coil
We are a focus on the production of switching power supplies and power adapters and other power products for high-tech enterprises. Shenzhen power adapter, power adapter manufacturers, switching power adapter, switching power supply manufacturers, charger manufacturers, USB power adapter, 12V power adapter
