- 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 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: 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 principle of capacitance isolation?
- When the capacitor is connected to the DC circuit, there will be a brief charging process. When the positive and negative plates are filled with charge (when the voltage across the capacitor is equal to the supply voltage), there is no current and then flow, so the capacitor is isolated DC current
- 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 to identify high voltage capacitors is good or bad
- You have no voltage regulator, if there is, with a voltage regulator, an ammeter a voltmeter (available multimeter instead) to the capacitor plus an integer current (controlled by a voltage regulator), and then calculate the capacitance based on the voltage reading and current reading Impedance, and then divided by 3184 calculated by the tolerance value, the results and the capacitor nameplate on the standard almost no capacitance, and the other side of the capacitor is broken
- Q: Why does the circuit current gradually decrease when charging the capacitor?
- due to the increase in the number of charge, the electrostatic field field strength will gradually increase, increasing the field strength caused by the absorption of electrons to produce exclusion, So that the number of adsorbed charges gradually reduced, the number of charge to reduce the performance of the phenomenon that the charging current is gradually reduced. When the number of charges on the two electrode plates of the capacitor reaches a gradually increasing field strength constraint, the amount of charge is not increased and the equilibrium state is reached, that is, the charge saturation current is zero.
- Q: Capacitance for AC and DC effects?
- This current is also a sine wave, but with the resistance is different, although there is voltage current, but does not consume energy, called reactive power.
- 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
- Q: What is the capacitor, what is the use, where is there?
- The role of the capacitor filter, coupling, bypass, decoupling function. Capacitors are mainly used for AC circuits and pulse circuits, in the DC circuit capacitors generally cut off the role of DC. Capacitors do not produce nor consume energy, are energy storage components.
