FAQ

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.
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.
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!
What is the phase-shifting capacitor, what is the difference between it and the general capacitor
And the phase-shifting capacitor has the function of changing the phase of the alternating current signal in addition to the characteristics of the general capacitor. The answer can be compensated by the power factor compensation in parallel with the phase-shifting capacitor, and the phase-shifting capacitor can be used to produce the phase-shifting capacitor fault diagnosis device.
How to use the capacitor
Solid-state aluminum capacitors have positive and negative points, do not reverse the solid-state aluminum capacitors, reverse solid capacitors can lead to a sharp increase in leakage current or reduced service life.
Why some Y capacitor is very small, and some Y capacitor is very large?
To charge the power cord for long periods of time. The safety standard stipulates that the voltage (or ground potential) charged at both ends of the power cord plug must be less than 30% of the original rated operating voltage within two seconds when the machine power cord is in operation.
What is the difference between the power capacitor and the complement?
A total of three-phase compensation at the same time, sub-compensation is a single-phase compensation.
Is the capacitor attached to the carbon foil positive?
The negative electrode of the capacitor is made of electrolyte, the electrolyte is generally composed of boric acid, ammonia, ethylene glycol and other components.
