Q:How does the capacitor work? What does it do?

Capacitance works: the principle of charge and discharge simply put the capacitor is the two poles charged or discharge, that is, charge diffusion. Charge and discharge capacitors should be connected in series, can be connected in parallel; it is the basis of other properties of capacitance. The phenomenon of intermittent communication is the embodiment of charge and discharge, if it is DC, charged to stop, the capacitor charged; if it is alternating current, is constantly charging discharge. Complete the transmission of AC.

Q:What are the differences between capacitors and capacitors?

Capacitance, resistance, inductance is physical quantity. Capacitors, resistors, inductors are components that have a specific physical quantity (capacitance, resistance, inductance).

Q:Is the capacitor attached to the carbon foil positive?

The above-mentioned positive and negative electrodes are wound around their central axis, and the core of the aluminum electrolytic capacitor is formed. Then, the core is placed in an aluminum shell and the aluminum electrolytic capacitor is formed.

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:On the ground resistance, what role the capacitor

Coupling: The capacitance used in the coupling circuit is called the coupling capacitor, which is used in the capacitive coupling amplifier and other capacitive coupling circuits to make use of this capacitor circuit.

Q:Use capacitance to do transformer how to calculate

According to this feature, if we connect a resistive element in series with a 1uF capacitor, the voltage obtained at both ends of the resistive element and the power dissipation it generates depends entirely on the characteristics of the resistive element.

Q:What is the capacitor, what is the use, where is there?

Capacitors are important devices in the power system to improve the power factor; in the electronic circuit is to obtain oscillation, filtering, phase shift, bypass, coupling and other major components of the role. Because the load used in the industry is mainly the motor inductive load, so the capacitor and the capacitive load to balance the power grid.

Q:Capacitance can pass high frequency resistance low frequency principle

When the negative half of the alternating current arrives, it will generate the current, first offset the original charge on the capacitor that the opposite charge, continue to charge to full.

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;

Q:Cd capacitance to express what

Generally speaking, no sense of capacitance mainly refers to the IGBT protection with the surge absorption capacitor, it is no sense of the structure. If used to prevent the power grid surge, of course, but it is too wasteful.
