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:Use capacitance to do transformer how to calculate

Capacitance buck method: For example, we will be a 110V / 8W bulb and a 1uF capacitor in series, received 220V / 50Hz AC voltage, the light bulb is lit, the normal brightness will not be burned. Since the 110V / 8W bulb requires a current of 8W / 110V = 72mA, it is consistent with the current limiting characteristics of the 1uF capacitor.

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

The capacitance of the symbol is C. In the international unit system, the capacitance of the unit is Farah, referred to as the law, the symbol is F. a capacitor, if the battery with a library when the potential difference between the two is 1 volt, the capacitor capacitor is 1

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: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 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: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:What is the difference between polyester film capacitors and ceramic capacitors?

Polyester capacitor medium for the polyester film, its capacity and pressure range, small size, large capacity, high temperature, low cost. But tgδ with the frequency changes, it is used for tgδ, stability and loss requirements are not high occasions, such as DC and pulsating circuit.

Q:What is the difference between the power capacitor and the complement?

Input compensation: three-phase co-fill capacitor input, the three groups of capacitors at the same time. The sub-capacitor can be put into operation separately.

Q:Capacitance can pass high frequency resistance low frequency principle

This process of current flow will soon end, the specific length of time and the resistance of the circuit and the size of the capacitor, the larger the size of the product the greater the charging time, the shorter the contrary. After charging is complete, the voltage across the capacitor is equal to the size of the DC supply voltage
