Q:What is the difference between the reactor and the capacitor?

Reactor is the inductance ah, usually magnetic components plus winding wound, storage of magnetic field energy, the capacitor is stored in the electric field energy.

Q:What is the electrolytic capacitor inside?

There are aluminum foil, paper (not the general paper), as well as electrolyte. There is polarity, then the explosion will explode.

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.

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 are the differences between capacitors and capacitors?

There is a capacitor is a unit of the capacitor is a substantial object ah

Q:How to use the capacitor

Circuites that are forbidden use: Even if the customer installs a solid-state aluminum capacitor in strict accordance with the welding conditions we have given, the leakage current of the solid-state aluminum capacitor may also increase or even increase significantly.

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: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:Why some Y capacitor is very small, and some Y capacitor is very large?

In line between the line of fire and zero line suppression capacitor, commonly known as X capacitance. As the location of the capacitor connection is also more critical, the same need to meet the relevant safety standards. X capacitance is also one of the safety capacitors. According to the actual needs, the capacitance value of the X capacitor is larger than the capacitance of the Y capacitor. However, it is necessary to connect a safety resistor in parallel with the X capacitor to prevent the charging and discharging of the power supply line.

Q:Why does the circuit current gradually decrease when charging the capacitor?

The capacitor is a charged container, when the container is full of charge when the internal potential and external potential can reach equilibrium, then the circuit of electrons no longer exercise.
