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:Does the size of the capacitor affect the power consumption?

Capacitors are essential electronic components, it acts as a smoothing filter in the electronic equipment, power supply and decoupling, AC signal bypass, AC-DC circuit AC coupling, etc. Because the type of capacitor and the type of structure more

Q:What is the electrolytic capacitor inside?

Electrolytic capacitor is a dielectric of a dielectric electrolyte coating has a polarity, positive and negative can not be connected wrong. Electric capacity (Electric capacity), by the two metal pole, the middle folder with insulating material (medium) composition.

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

Straight to pass on the circuit need to pass the AC signal, power supply filter, cut off DC and other places to use. Capacitor charge and discharge is the basis of other properties. There are two kinds of filtering, one is the power filter, which is more obvious charge and discharge, can be seen as a container.

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?

The paper dielectric is made of two pieces of metal foil, made of very thin capacitor paper, rolled into a cylindrical or flat cylindrical core, and then sealed in a metal shell or insulating material (such as paint, ceramics, glass glaze, etc.) production. It is characterized by a smaller size, capacity can be done bigger. But there are inherent inductors and losses are relatively large, suitable for low frequency.

Q: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.

Q:Capacitance for AC and DC effects?

In the sine wave AC circuit, the current size of the current flowing through the capacitor can be quantitatively calculated. Specifically, the voltage U is in volts (V), the current I is in the unit (A), the capacitance C is expressed by the law (F) (Ω), the frequency of the AC power supply is expressed in Hertz (Hz) units, and the frequency of the AC power supply is expressed in Hits (Hz)

Q:How to identify high voltage capacitors is good or bad

You have no voltage regulator, if there is, with a voltage regulator, an ammeter a voltmeter (available multimeter instead) to the capacitor plus an integer current (controlled by a voltage regulator), and then calculate the capacitance based on the voltage reading and current reading Impedance, and then divided by 3184 calculated by the tolerance value, the results and the capacitor nameplate on the standard almost no capacitance, and the other side of the capacitor is broken

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.
