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 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:Does anyone know the difference between the stray inductance of the capacitor and the parasitic inductance?: This impedance can not be ignored in the presence of high frequency current, with particular note that the bypass capacitor needs to pass through the two vias when connecting the power plane and the formation so that the parasitic inductance of the vias is multiplied.

Q:What kind of capacitance can be divided into?: Capacitors are often called capacitors. According to its structure can be divided into fixed capacitors, semi-variable capacitors, variable capacitors three.

Q:Is the capacitor attached to the carbon foil positive?: In order to facilitate the manufacture of capacitors, usually the electrolyte solution is immersed in special paper, and then with a place of aluminum and immersion in electrolyte solution with the paper together, so you can more easily in the original aluminum foil to lead the negative.

Q:Capacitance for AC and DC effects?: Potential has a concept of space, referring to the electric field to a Coulomb charge from A to B work 1 joules, A on the B potential is 1 volt. The concept of potential for the circuit, specify a point of the circuit for the 0 potential, the other points are based on the point of the voltage is the potential of the other points. Electromotive force used in batteries, generators, is the power to generate voltage.

Q:On the ground resistance, what role the capacitor: The capacitor used in the bypass circuit is called the bypass capacitor. If the signal is removed from the signal in the circuit, the bypass capacitor circuit can be used. According to the frequency of the removed signal, there is a full frequency domain (all AC signals ) Bypass capacitor circuit and high frequency bypass capacitor circuit.

Q:Use capacitance to do transformer how to calculate: The principle of capacitor buck is not complicated. His working principle is to use the capacitor at a certain AC signal frequency to produce capacitive reactance to limit the maximum operating current. For example, in the 50Hz frequency conditions, a 1uF capacitance generated by the capacitive reactance of about 3180 ohms. When 220V AC voltage is applied to both ends of the capacitor, the maximum current flowing through the capacitor is about 70mA.

Q:How to identify high voltage capacitors is good or bad: This is a special place for high voltage capacitors in microwave ovens. Because in this capacitor in parallel with a 10M capacitor. So the capacitor does not leak when the final resistance is 10M. Not infinity

Q:Low voltage capacitor voltage 0.45 and 0.4 What is the difference between usage: 0.45 and 0.4 capacitors are capacitors that rated the line voltage of 0.45kV and 0.4kV; they are suitable for 380V voltage systems, the difference lies in their pressure rating;
