Q:How to select power adapter
The polarity of your notebook symbol is in the negative, the adapter of my pictures is not clear what is marked polarity
Q:What is the power adapter
because the home that is a supply voltage of 220 volts, and electronic products generally generally required supply voltage is 5 volts to 20 volts.
Q:Main parameters of inductor
Usually, the more coils, the more dense the winding, the greater the inductance
Q:What is the inductance component
Inductor also known as inductance coil, is the use of electromagnetic induction principle
Q:Why use inductance
transformer can exchange coupling, variable pressure and variable flow and impedance transformation etc..
Q: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.
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:Inductance and capacitance how to understand?
The interaction between the current and the coil is called electrical impedance, inductance is, unit is Henry (H), named after the American scientist Joseph Henry.
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
Q:Inductance has no direction?
To discuss the situation: in the general filter circuit, the direction is not large; but if used in the PWM output inductance, this direction is too critical.
