Q:The value of the inductance is determined by what

It was also reduced the Q value of the inductor, the purpose is to avoid high frequency resonance / gain is too large

Q:Linear adapter and switching power adapter

Linear power supply refers to the adjustment of the power supply pipe in a linear state, while the switching power supply regulator works in the switch state

Q:Inductance has no direction?

When the reverse will appear inductance direction.

Q:Why inductors do not consume electricity

When the inductor is connected with the direct current, the inductance is charged, and the charge which is filled with the inductance two will never disappear

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:Inductance is the sensor?

When the coil passes through the current, a magnetic field is formed in the coil, and the induced magnetic field generates an induced current to resist the current flowing through the coil.

Q:Inductance and capacitance how to understand?

capacitance (Capacitance), also known as "capacitance" refers to the given potential difference between the amount of charge storage, denoted as C, the international unit is Fala (F)

Q: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)

Q:Is Australia's power adapter the same as Europe?

Voltage is 240V, voltage is based on the country, China is 220V, the United States and Canada is 110V

Q:Laptop power adapter are AC-DC dual-use

l, a power transformer and rectifier circuit, the working power supply of AC (alternating current standard in China for the exchange of 220V),
