- What is the inductance component
- The inductor is composed of skeleton, winding, shield, packaging material, core or core.
- How to determine whether the computer adapter is available
- Today, there is a typhoon, the home of electricity is not stable, there will be no electricity for a while, and then I charge the laptop in the process, the computer did not boot
- 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.
- 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.
- What is the difference between the ballast and the adapter
- but the ballast is the special power supply of fluorescent lamp (electrical characteristics of fluorescent lamp special)
- What is the substitution principle of inductance?
- If the inductor is in the absence of an electric current, it will try to block the current flowing through it when the circuit is switched on; if the inductor is in the state of current passing, it will try to keep the current constant when the circuit is disconnected.
- What is the inductance
- most of the enameled wire (or wire) around the skeleton, then the inner core or copper core into the heart, skeleton, to increase its inductance.
- What is a power adapter, what is the use of
- generally consists of a shell, a power transformer and rectifier circuit, according to the type of output can be divided into AC output type and DC output type; according to connection can be divided into the plug wall and desktop
