- 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: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: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 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 relationship between capacitance and voltage?
- In your case, you can think of two capacitors as two containers, 5v capacity than 10v half (because they are 0.01uF),
- Q:What is the electrolytic capacitor inside?
- Electrolytic capacitor inside the composition of the structure: two close to each other with a coating with polarity, positive and negative metal electrode plate, the middle folder with insulating material (medium for the electrolyte,) constitute
- Q:Low voltage capacitor voltage 0.45 and 0.4 What is the difference between usage
- Can be used in the low-voltage three-phase power lines on the line, but the level of different pressure, connected to the 400V line, 450V capacitor capacity is 79% of rated capacity, 400V capacitor capacity is rated capacity. In the use of life on the 450V longer than 400V
- Q:Why some Y capacitor is very small, and some Y capacitor is very large?
- In line between the line of fire and zero line suppression capacitor, commonly known as X capacitance. As the location of the capacitor connection is also more critical, the same need to meet the relevant safety standards. X capacitance is also one of the safety capacitors. According to the actual needs, the capacitance value of the X capacitor is larger than the capacitance of the Y capacitor. However, it is necessary to connect a safety resistor in parallel with the X capacitor to prevent the charging and discharging of the power supply line.
- 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:How to judge the capacitor is good or bad?
- 10pF below the fixed capacitor capacity is too small, with a multimeter to measure, only qualitative check whether there is leakage, internal short circuit or breakdown phenomenon.
