Q:What is the difference between the reactor and the capacitor?

Reactor is the inductance ah, usually magnetic components plus winding wound, storage of magnetic field energy, the capacitor is stored in the electric field energy.

Q:Does the size of the capacitor affect the power consumption?

Capacitors are essential electronic components, it acts as a smoothing filter in the electronic equipment, power supply and decoupling, AC signal bypass, AC-DC circuit AC coupling, etc. Because the type of capacitor and the type of structure more

Q:What is the phase-shifting capacitor, what is the difference between it and the general capacitor

Assuming a capacitor has upper and lower poles, the upper plate is connected with the positive pole, the lower plate is connected with the negative electrode, connected with the power source, the potential difference between the two plates is formed, and the potential difference between the two electrodes is equal,

Q:What is the use of capacitors?

As a passive component of the capacitor, its role is nothing more than the following; applied to the power circuit, to achieve bypass, decoupling, filtering and energy storage role, the following classification:

Q:What is the principle of capacitance isolation?

When the capacitor is connected to the AC circuit, there is also a charging process in which the charge is stopped when the capacitor voltage is equal to the supply voltage, and then the power supply voltage drops and the capacitor begins to discharge.

Q:Is the capacitor attached to the carbon foil positive?

In order to facilitate the manufacture of capacitors, usually the electrolyte solution is immersed in special paper, and then with a place of aluminum and immersion in electrolyte solution with the paper together, so you can more easily in the original aluminum foil to lead the negative.

Q:What is the relationship between capacitance and voltage?

when you charge 5v, want to be in the first The capacitor is full, the second capacitor half; if you charge a higher voltage 6v, then the first capacitor to diffuse out, the actual performance of the capacitor was breakdown!

Q:Why some Y capacitor is very small, and some Y capacitor is very large?

They all belong to the safety capacitor, which requires the capacitance value can not be too large, and the pressure must be higher. Under normal circumstances, work in the subtropical machine, the required leakage current can not exceed 0.7mA; work in the temperate machine, the required leakage current can not exceed 0.35mA. Therefore, the total capacity of the Y capacitor is generally not more than 4700PF (472).

Q:Why does the circuit current gradually decrease when charging the capacitor?

due to the increase in the number of charge, the electrostatic field field strength will gradually increase, increasing the field strength caused by the absorption of electrons to produce exclusion, So that the number of adsorbed charges gradually reduced, the number of charge to reduce the performance of the phenomenon that the charging current is gradually reduced. When the number of charges on the two electrode plates of the capacitor reaches a gradually increasing field strength constraint, the amount of charge is not increased and the equilibrium state is reached, that is, the charge saturation current is zero.

Q:Cd capacitance to express what

Mainly speaking, the winding process of the capacitor is a non-inductive winding structure (relative, there is a sense of winding structure), in fact, no sense of capacitance is not no inductance, but the inductance is very small, for high-frequency operation of the capacitor, We emphasize no sense. In fact, the inductance is small. From this point of view, almost all of the metal film capacitors are no sense
