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

Straight to pass on the circuit need to pass the AC signal, power supply filter, cut off DC and other places to use. Capacitor charge and discharge is the basis of other properties. There are two kinds of filtering, one is the power filter, which is more obvious charge and discharge, can be seen as a container.

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

As long as connected to the power, there is an electric field circuit, or how to move the electronic. Remember that the point of connection with the wire is equal, the beginning, the pole and the power of the positive potential, the lower plate and the negative potential, potential difference is not zero, the formation of electric field, electronic movement, The plates are connected by wires, and the electrons move through the wires. The answer is not the same Oh, the terminal distribution of the low-voltage power distribution room is thousands of capacitors Oh, is not the same! Answer Replenishment Phase Capacitor Cabinet Concentrates the compensation power factor at the low voltage side of the transformer.

Q:What are the differences between capacitors and capacitors?

There is a capacitor is a unit of the capacitor is a substantial object ah

Q:What kind of capacitance can be divided into?

Aluminum electrolytic capacitor It is made of aluminum cylinder negative, which is equipped with liquid electrolyte, insert a curved aluminum belt made of positive electrode. Also need to go through the DC voltage treatment, so that the formation of an oxide film on the positive film to do the media. It is characterized by large capacity, but large leakage, large error, poor stability, often used for AC bypass and filter, when the request is not high when used for signal coupling. Electrolytic capacitors are positive and negative points, the use can not be reversed. There are positive and negative polarity, the use of time, positive and negative do not reverse.

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

Electrolytic capacitors of the positive plate with aluminum foil, immersed in the electrolyte for anodic oxidation treatment, aluminum foil surface will produce a layer of aluminum oxide film, the thickness is generally 0.02 - 0.03μm. This layer of oxide film is positive and negative insulation between the plates.

Q:On the ground resistance, what role the capacitor

Filter: The capacitor used in the filter circuit is called the filter capacitor, in the power supply filter and a variety of filter circuit using this capacitor circuit, filter capacitor will be a certain band of the signal from the total signal removed.

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

Why does the circuit current gradually decrease when charging the capacitor? Because the charge began to charge the capacitor, the capacitor two electrode plate charge began to zero, the electrostatic field is zero, the absorption of electrons is not exclusion, the performance of the phenomenon is the beginning of the charge when the circuit current is very large, with the capacitor The charging time increases, there will be more and more charge adsorption on the capacitor two electrode plates,

Q:Capacitance can pass high frequency resistance low frequency principle

The capacitor has a charge and discharge time problem. When the positive half of the AC, to the capacitor charging moment, the circuit is a current flow, the equivalent of the channel, once the capacitor is charged, the circuit will not flow through, the equivalent of open circuit.

Q:What is the difference between the power capacitor and the complement?

A total of three-phase compensation at the same time, sub-compensation is a single-phase compensation.

Q:Cd capacitance to express what

Generally speaking, no sense of capacitance mainly refers to the IGBT protection with the surge absorption capacitor, it is no sense of the structure. If used to prevent the power grid surge, of course, but it is too wasteful.
