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

Reactor is the inductive load, there are series and parallel in series, the series is mainly used to limit the short-circuit current, parallel mainly used for ultra-high voltage long-distance transmission, the compensation line capacitance. Capacitors are capacitive loads that are used primarily to compensate for reactive and energy storage. Inductance and capacitance combinations for filtering and so on.

Q:How does the capacitor work? What does it do?

Capacitance works: the principle of charge and discharge simply put the capacitor is the two poles charged or discharge, that is, charge diffusion. Charge and discharge capacitors should be connected in series, can be connected in parallel; it is the basis of other properties of capacitance. The phenomenon of intermittent communication is the embodiment of charge and discharge, if it is DC, charged to stop, the capacitor charged; if it is alternating current, is constantly charging discharge. Complete the transmission of AC.

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 difference between polyester film capacitors and ceramic capacitors?

Ceramic dielectric (type CC) ceramic material dielectric constant ε is very large, so the capacitor volume can be made very small.

Q:What kind of capacitance can be divided into?

Oil and paper capacity. It is the paper dielectric capacitor immersed in a specially treated oil, can enhance its pressure. It is characterized by large capacity, high pressure, but the larger. Glass glaze capacitors to glass glaze for the media, with the advantages of ceramic capacitors, and smaller, high temperature.

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?

The above-mentioned positive and negative electrodes are wound around their central axis, and the core of the aluminum electrolytic capacitor is formed. Then, the core is placed in an aluminum shell and the aluminum electrolytic capacitor is formed.

Q:On the ground resistance, what role the capacitor

High-frequency vibration elimination: the capacitor used in the high-frequency vibration circuit called high-frequency vibration capacitor, in the audio negative feedback amplifier, in order to eliminate the vibration may occur high-frequency self-excited, the use of this capacitor circuit to eliminate the amplifier Possible high frequency whistling

Q:How to identify high voltage capacitors is good or bad

Test the resistance at both ends with a multimeter. If the use of a pointer multimeter, and most of the same capacitor, you can see the pointer from small to large a swing process. The difference is not the last return to infinity, but 10m. Inexperienced friends may think that the capacitor breakdown or leakage, in fact, not.

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.
