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

Capacitors in order to boost, so that the voltage ahead; reactor in order to buck, so that the voltage lag; they are in the system are reactive power, improve power quality

Q:What is the phase-shifting capacitor, what is the difference between it and the general capacitor

The lower plate with a negative, so that the formation of potential difference between the two poles. And the positive charge does not move, only the negative charge - the electron will move, so the electrons along the plate along the wire, the power positive - negative move to the lower plate, so that the two plates will bring dissimilar charge. With the movement of electrons, the charge of the bipolar plate is more and more, the voltage is getting bigger and bigger, and the power supply potential difference is equal, it is full of electricity.

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 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:Is the capacitor attached to the carbon foil positive?

Electrolytic capacitors of the positive plate with aluminum foil, immersed in the electrolyte for anodic oxidation treatment, aluminum foil surface will produce a layer of aluminum oxide film, the thickness is generally 0.02 - 0.03μm. This layer of oxide film is positive and negative insulation between the plates.

Q:How to use the capacitor

The sum of the DC voltage and the ripple peak voltage shall not exceed the rated operating voltage;

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: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: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.

Q:What is the capacitor, what is the use, where is there?

Capacitor is the storage of the charge of the container, usually by two pieces of metal foil (or metal film) in the interval between the air, paper, mica, plastic film and other insulating materials. Commonly used to improve the power factor, start single-phase asynchronous motor,
