Q:What are the two functions of the inductor in the circuit

it will hinder the current increase of electric energy in the magnetic field in the form of temporary storage

Q:How to select power adapter

he same or similar voltage. The nominal input voltage on your computer is 16V, and the rated output voltage of the adapter is 20V, the difference is larger, so it can not be replaced

Q:Inductance has no direction?

When the reverse will appear inductance direction.

Q:The role of inductance in the circuit

On the basis of Lenz's law, the magnetic flux will borrow the voltage by induction (EMF) and tend to resist a change in current. The ratio of change in magnetic flux changing the amount of current is called self inductance,

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 inductance

The inductor is composed of skeleton, winding, shield, packaging material, core or core.

Q:Inductance is the sensor?

The interaction between the current and the coil is called electrical impedance, inductance is, unit is Henry (H)"

Q:What is the inductor

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

Q: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

Q:What is the difference between the ballast and the adapter

its essence is the ballast power supply circuit
