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: What are the differences between capacitors and capacitors?: There is a capacitor is a unit of the capacitor is a substantial object ah

Q: Use capacitance to do transformer how to calculate: Similarly, we can also 5W / 65V bulb and 1uF capacitor series connected to the 220V / 50Hz AC, the bulb will be lit, and will not be burned. Because the 5W / 65V bulb operating current is also about 70mA. Therefore, the capacitor buck is actually using capacitive current limiting. While the capacitor actually functions as a limiting current and dynamically distributes the voltage across the capacitor and the load.

Q: What is the phase-shifting capacitor, what is the difference between it and the general capacitor: After the power is turned off, the charge will not disappear, nor will it be neutralized (after all, between the two plates is insulated, positive and negative charge can only attract each other, and can not be combined), so that the potential difference has been there until you To discharge, the bipolar plate with a wire, the electrons along the wire from the lower plate to move to the upper plate, the potential difference disappeared.

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.

Q: What is the difference between the power capacitor and the complement?: Wiring, three-phase complementary capacitor has three terminals, respectively (A, B, C) sub-capacitor has four terminals, respectively, then

Q: Does anyone know the difference between the stray inductance of the capacitor and the parasitic inductance?: This impedance can not be ignored in the presence of high frequency current, with particular note that the bypass capacitor needs to pass through the two vias when connecting the power plane and the formation so that the parasitic inductance of the vias is multiplied.

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 does the capacitor work? What does it do?: The other is the signal filter, that is, the case of alternating current, but also in the AC electrode polarity changes in the process of continuous charge and discharge, in order to AC, if not the capacitance of the two sheds with the amount of change, no matter how the AC can not pass.

Q: What is the difference between polyester film capacitors and ceramic capacitors?: Good stability. From the chemical performance, acid, alkali, salt and water corrosion of ceramic materials is very small, from the heat resistance, the ceramic material in the high temperature of up to 500 ~ 600 ℃, long-term work without aging
