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 is the use of capacitors?

As a passive component of the capacitor, its role is nothing more than the following; applied to the power circuit, to achieve bypass, decoupling, filtering and energy storage role, the following classification:

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

Ceramic dielectric (type CC) ceramic material dielectric constant ε is very large, so the capacitor volume can be made very small.

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: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

Decoupling: The capacitor used in the decoupling circuit is called the decoupling capacitor. This capacitor circuit is used in the DC voltage supply circuit of the multi-stage amplifier. The decoupling capacitor eliminates the harmful low frequency cross-connection between the amplifiers.

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:How to identify high voltage capacitors is good or bad

There is a series in 220v AC power inside, see if the light bulb can be normal light. Determine if the capacitor has capacity. Whether the initial test is normal.

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.
