- Q: How to use the capacitor
- Circuites that are forbidden use: Even if the customer installs a solid-state aluminum capacitor in strict accordance with the welding conditions we have given, the leakage current of the solid-state aluminum capacitor may also increase or even increase significantly.
- 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: Cd capacitance to express what
- Mainly used in high voltage, high current and high pulse circuit, such as buffer, energy converter, switching power supply, inverter and inverter protection circuit, especially for IGBT, SCR, Darlington line For absorption capacitors.
- Q: Does the size of the capacitor affect the power consumption?
- Therefore, users not only need to understand the performance of various types of capacitors and general characteristics, but also must understand the advantages and disadvantages of various components under given use, mechanical or environmental constraints, etc. This article describes the main parameters of the capacitor and application , For readers to choose the type of capacitor used.
- Q: How to judge the capacitor is good or bad?
- Measurement, the choice of multimeter R × 10k block, with two test leads were any then the capacitor of the two pins, the resistance should be infinite. If the measured resistance (pointer to the right swing) is zero, then the capacitor leakage damage or internal breakdown.
- 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?
- 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: What is the use of capacitors?
- As a passive component of the capacitor, its role is nothing more than the following; applied to the power circuit, to achieve bypass, decoupling, filtering and energy storage role, the following classification:
- Q: What is the difference between polyester film capacitors and ceramic capacitors?
- The frequency characteristics of the capacitor is better than the polyester, the capacitance and tgδ with the frequency of small changes can be used in low-voltage AC-DC circuit.
- 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.
