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?

The capacitance is the physical quantity that characterizes the capacity of the capacitor to charge the charge.We charge the capacitance of the capacitor by increasing the potential difference between the two plates of the capacitor by one volt.

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 principle of capacitance isolation?

When the capacitor is connected to the DC circuit, there will be a brief charging process. When the positive and negative plates are filled with charge (when the voltage across the capacitor is equal to the supply voltage), there is no current and then flow, so the capacitor is isolated DC current

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?

Current waveform ahead of the voltage 90 degrees, in a sine wave cycle, half of the time ( Voltage waveform 0-90 degrees and 180-270 degrees) power to charge the capacitor, while the other half of the time (voltage waveform 90-180 degrees and 270-0 degrees) capacitance of the power discharge, the power and intact return power The

Q:What is the relationship between capacitance and voltage?

In your case, you can think of two capacitors as two containers, 5v capacity than 10v half (because they are 0.01uF),

Q:Use capacitance to do transformer how to calculate

The principle of capacitor buck is not complicated. His working principle is to use the capacitor at a certain AC signal frequency to produce capacitive reactance to limit the maximum operating current. For example, in the 50Hz frequency conditions, a 1uF capacitance generated by the capacitive reactance of about 3180 ohms. When 220V AC voltage is applied to both ends of the capacitor, the maximum current flowing through the capacitor is about 70mA.

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

At the AC power input, it is generally necessary to add three safety capacitors to suppress EMI conduction interference. AC power input is divided into three terminals: FireWire (L) / Neutral (N) / Ground (G). Between the line of fire and the ground and between the zero line and ground in parallel with the capacitor, generally referred to as Y capacitor. The two Y-capacitor connection position is more critical, must meet the relevant safety standards, to prevent electronic equipment leakage or chassis charged, easy to endanger personal safety and life.

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.
