Q:What is the capacitor, what is the use, where is there?
In the electronic technology, used to consider the wave, phase, straight, bypass, frequency, etc. Almost all of the electronic products, household appliances are the following are some of the capacitor shape.
Q:How does the capacitor work? What does it do?
The bypass capacitor is an energy storage device that provides energy to the local device, which can equalize the output of the regulator and reduce the load demand. Like a small rechargeable battery, the bypass capacitor can be charged and discharged to the device. To minimize the impedance, the bypass capacitor should be as close as possible to the load device's power supply pin and ground pin.
Q:Why some Y capacitor is very small, and some Y capacitor is very large?
As a capacitor of the Y capacitor, it is required to obtain the certification of the safety inspection mechanism. Y capacitor appearance is mostly orange or blue, are generally marked with safety certification mark (such as UL, CSA and other logo) and pressure AC250V or AC275V words. However, its true DC withstand voltage is above 5000V. It must be emphasized that the Y capacitor can not be used with a nominal capacitor such as the nominal voltage AC250V or DC400V.
Q:Why does the circuit current gradually decrease when charging the capacitor?
Why does the circuit current gradually decrease when charging the capacitor? Because the charge began to charge the capacitor, the capacitor two electrode plate charge began to zero, the electrostatic field is zero, the absorption of electrons is not exclusion, the performance of the phenomenon is the beginning of the charge when the circuit current is very large, with the capacitor The charging time increases, there will be more and more charge adsorption on the capacitor two electrode plates,
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:What is the relationship between capacitance and voltage?
when you charge 5v, want to be in the first The capacitor is full, the second capacitor half; if you charge a higher voltage 6v, then the first capacitor to diffuse out, the actual performance of the capacitor was breakdown!
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 kind of capacitance can be divided into?
Commonly used capacitor structure and characteristics Commonly used capacitors can be divided into their dielectric materials electrolytic capacitors, mica capacitors, ceramic capacitors, glass glaze capacitors 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: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.
