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

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:What are the differences between capacitors and capacitors?

Capacitance is a large category, and capacitors are subclasses of capacitors. Capacitors can be divided into cbb capacitors, aluminum electrolytic capacitors, safety capacitors and so on. Different categories, the difference is still relatively large

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:Use capacitance to do transformer how to calculate

Capacitance buck method: For example, we will be a 110V / 8W bulb and a 1uF capacitor in series, received 220V / 50Hz AC voltage, the light bulb is lit, the normal brightness will not be burned. Since the 110V / 8W bulb requires a current of 8W / 110V = 72mA, it is consistent with the current limiting characteristics of the 1uF capacitor.

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 capacitor, what is the use, where is there?

Capacitor is the storage of the charge of the container, usually by two pieces of metal foil (or metal film) in the interval between the air, paper, mica, plastic film and other insulating materials. Commonly used to improve the power factor, start single-phase asynchronous motor,

Q:Capacitance can pass high frequency resistance low frequency principle

This process of current flow will soon end, the specific length of time and the resistance of the circuit and the size of the capacitor, the larger the size of the product the greater the charging time, the shorter the contrary. After charging is complete, the voltage across the capacitor is equal to the size of the DC supply voltage

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

In fact, in the case of three-phase imbalance, but also a total complement and sub-all have, the three-phase power factor, respectively, 0.53,0.67,0.71, then, in the 0.71 above this part, The reactive power required by the other parts of the two phases is compensated by tipping.

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.
