Q:Capacitance can pass high frequency resistance low frequency principle
In a cycle of alternating current, due to the positive and negative charge of the capacitor, the direction of the current flowing through the circuit is changed, but because of the repeated charge and discharge of the capacitor, the circuit will always have a current through, Can make the AC through, which is the capacitance of the communication characteristics.
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: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.
Q:What is the difference between the reactor and the capacitor?
Capacitors in order to boost, so that the voltage ahead; reactor in order to buck, so that the voltage lag; they are in the system are reactive power, improve power quality
Q:What are the differences between capacitors and capacitors?
Capacitance is a large category, and capacitors are subclasses of capacitors. Capacitors can be divided into cbb capacitors, aluminum electrolytic capacitors, safety capacitors and so on. Different categories, the difference is still relatively large
Q:Does anyone know the difference between the stray inductance of the capacitor and the parasitic inductance?
In the design of high-speed digital circuits, the parasitic inductance of the vias is often more harmful than the parasitic capacitance. Its parasitic series inductance will weaken the contribution of the bypass capacitor, reducing the filtering efficiency of the entire power system. We can use the following formula to simply calculate a parasitic inductance of a vias:
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:Use capacitance to do transformer how to calculate
Although the current flowing through the capacitor has 70mA, but in the capacitor does not produce power, because if the capacitor is an ideal capacitor, the current flowing through the capacitor for the virtual part of the current, the work done by the reactive power.
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: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.
