Q:Does the size of the capacitor affect the power consumption?: The capacitance is the physical quantity that characterizes the capacity of the capacitor to charge the charge.We charge the capacitance of the capacitor by increasing the potential difference between the two plates of the capacitor by one volt.

Q:Cd capacitance to express what: No capacitance is used in the high-frequency circuit of a capacitor, this capacitor without pins or pins shorter, commonly used in the tuner; generally PF level, the so-called "no sense" is the capacitor work is not produce "inductance" Effect, because C (capacitance) + L (inductance) = R (resistance), (when the match is good), if so, the circuit will not work.

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 kind of capacitance can be divided into?: The paper dielectric is made of two pieces of metal foil, made of very thin capacitor paper, rolled into a cylindrical or flat cylindrical core, and then sealed in a metal shell or insulating material (such as paint, ceramics, glass glaze, etc.) production. It is characterized by a smaller size, capacity can be done bigger. But there are inherent inductors and losses are relatively large, suitable for low frequency.

Q:What is the electrolytic capacitor inside?: Electrolytic capacitor features three: the price than other types have overwhelming advantages, because the composition of electrolytic capacitors are common industrial materials, such as aluminum and so on.

Q:What is the phase-shifting capacitor, what is the difference between it and the general capacitor: The lower plate with a negative, so that the formation of potential difference between the two poles. And the positive charge does not move, only the negative charge - the electron will move, so the electrons along the plate along the wire, the power positive - negative move to the lower plate, so that the two plates will bring dissimilar charge. With the movement of electrons, the charge of the bipolar plate is more and more, the voltage is getting bigger and bigger, and the power supply potential difference is equal, it is full of electricity.

Q:Low voltage capacitor voltage 0.45 and 0.4 What is the difference between usage: 0.45 and 0.4 capacitors are capacitors that rated the line voltage of 0.45kV and 0.4kV; they are suitable for 380V voltage systems, the difference lies in their pressure rating;

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: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:What is the difference between the power capacitor and the complement?: Input compensation: three-phase co-fill capacitor input, the three groups of capacitors at the same time. The sub-capacitor can be put into operation separately.
